`gions, and at least two among the regions may have dif—
`ferent areas. As an example, the substrate SUB may
`have two regions, and the two regions may have areas
`different from each other. As another exampie, the sub—
`strate SUB may have three regions. in this case, all of
`the three regions may have areas different from one an—
`other. or two regions among the three regions may have
`same areas and the other one region may have an area
`different from the two regions. As still another example,
`the substrate SUB may have four or more regions.

`connected to the t'rst pixel region PXA’l. in other words,
`one side of the second pixel region PXA2 may contact
`one side of the first pixel region PXAt.
`[6037} The second peripheral region PPAZ may be
`provided at at least one side of the second pixei region
`PXA2.
`in an embodiment of the present disclosure, the
`second peripherai region PPAZ surrounds the second
`pixel region PXAZ, but may not be provided at a portion

`and the third width WS may he equal to each other. in
`addition. the second length L2 and the third length L3
`may be equal to each other.
`[@1245] The third pixel region PXAB is provided in a
`shape protruding from the first pixel region PXAt, and
`may be directly connected to the first pixel region PXM.
`in other words, one side of the third pixel region PXAS
`may contact one side of the first pixel region PXAl

`[GMZE
`in an embodiment ofthe present disclosure, the
`third region A3 may have a shape line symmetric to the
`second region A2 with respect to a center line of the f'rst
`region A1, in this case, the arrangement or' components
`provided in the third region A3. may be substantially iden-
`tical to that in the second region A2 except some lines
`[9043} Therefore,
`the substrate SUB may have a
`shape in which the second region A2 and the third region
`A3 protrude in the second direction [3R2 from the first
`region A’l.
`in addition, since the second region A2 and
`the third region A3 are disposed to be spaced apart from
`each other, the substrate SUB may have ashape in which
`it is depressed between the second region A2 and the
`third region A3. That is, the substrate SUB may have a
`notch between the second region A2 and the third regior
`'2
`
`in an embodiment ofthe present disclosure. the
`[9044}
`longitudinal parts ofthe first peripheral region PPM may
`be respectively connected to some of the longitudinal
`parts of the second peripheral region PPAZ and the third
`peripheral region PPAS. For example, a left longitudinal
`part oftheflrst peripheral region PPA’i may be connected
`to a left longitudinal part of the second peripheral region
`PPAE. A right longitudinal part or’ the first peripheral re-
`gion PPM may be connected to a right longitudinal part
`of the third peripheral region PPA3.
`in addition, the left
`longitudinal part of the first peripheral region PPA‘: and
`the left longitudinal part of the second peripheral region
`
`or

`
`GPA?! may have the same width W4. The right longitudi—
`nal part otthe first peripheral region PPA‘l and the right
`longitudinal part of the third peripheral region PPAfj‘ may
`have the same width W5.
`
`[90453 The width W4 ofthe left longitudinal parts of the
`first peripheral region PPM and the second peripheral
`region l-"f-"AZ may be different from the width W5 of the
`right longitudinal parts ofthe first peripheral region PPM
`and the third peripheral region PPAS. For example, the
`width W4 ofthe left longitudinal parts ofthe first peripheral
`region PPAt and the second peripheral region PPAQ may
`be smaller than the width W5 of the right longitudinal
`parts of the first peripheral region PPA’: and the third
`peripheral region PPAE.

`in an emhodl. tent of the presentdlsclosure, the
`substrate SUB may further include an additional periph—
`eral region APA. The additional peripheral region APA
`may he provided adjacent to the first pixel region PXAt,
`the second peripheral region PP‘AE, and the third periph—
`eral region PPAii. Forexample, the additional peripheral
`region APA may connect the second peripheral region
`PPAZ to the third peripheral region PPAE». For example,
`the additional peripheral region APA may connect a right
`longitudinal part of the second peripheral region Pit-7A2
`to a left longitudinal part of the third peripheral region
`PPAS. That is, the additional peripheral region APA may
`he provided at a side of the first pixel region PXAt be--
`tween the second region A2 and the third region A3.

`is a minimum unit for displaying an image, and a plurality
`of pixels PXL may be provided in the first to third pixel
`regions PXAl, PXAZ, and PXA3, The pixels PXL may
`include a display element that emits light. For example,
`the display element may be any one of a liquid crystal
`display (LCD) element, an electrophoretic display (El-‘0)
`element, an eiectrowetting display (EWD) element, and
`an organic lig
`emitting display (OLE-D) element. Mean—

`[9949} The pixels PXL may include first pixels PXL’:
`arranged in the first pier region PXAl, second pixels
`PXLZ arranged in the second pixel region PXAE, and
`third pixels PXLS arranged in the third pixel region PXAS.
`In an embodiment ofthe present disclosure, each of the
`first to third pixels PXLt, PXLZ, and PXLS may be pro-
`vided in plurality to he arranged in a matrix form along
`rows extending in the first direction Dl-‘t’l and columns
`extending in the second direction DRE. However, the ar—
`rangeme
`of the first to third pixels PXLt, PXL2, and
`PXLS is not particularly limited, and the first to third pixels
`PXLt, PXLZ. and PXLB may be arranged in various

`forms. For example, the first pixeis PXL’: may be ar-
`ranged such that the firstdireotion DRi becomes the row
`direction, but the second pixeis F’XLE may be arranged
`along a direction different from the first direction DR'l,
`e.g., a direction oblique to the first direction DRi may
`become the row direction. In addition, it t. 'iii be apparent
`that the third pixels FJXLS may be arranded in a dire .tion
`identical to or different from that of the first pixels PXLt
`and/or the second pixels PXLE. Alternatively, in another
`embodiment of the present disclosure, the row direction
`may become the second direction. 0R2. and the colurn n
`may become the first direction 0R1.

`in the second region A2 and the
`third region A3, the number of second pixeis PXLZ and
`third pixels PXLE may be changed depending on rows.
`More specifically, the second region A2 and the third re-
`gion A3 may include a first sub—region and a second sub—
`region, and in the second region A2 and the third region
`
`A3, the iength ofa row disposed in the second sub—region
`may be greater than that of a row disposed in the first
`sub—region. The number of second pixsis PXLZ? and third
`pixels PXLS, which are arranged on the row, may be de—
`creased as the length of the row is shortened. Therefore
`in the second region A2 and the third region A3, the
`number of second pixels PXL2 and third pixels PXLS.
`which are arranged on a row disposed in the second sub-
`region. may be smaller than that of second pixels PXL2
`and third pixeis PXLE, which are arranged on a row dis--
`posed in the first sub-region. in addition, as the length of
`the row is shortened, the iengths of lines for connecting
`the second pixels F’XLE and the third pixels PXL3 may
`be shortened.

`in an embodiment ofthe presentdisclosure, the
`scan drivers SDV may be directly mounted on the sub-
`strate SUB. When the. scan drivers SDV are directiy
`mounted on the substrate SUB, the scan drivers SDV
`may he formed togethert 'ith the pixeis PXL in a process
`of forming the pixels PXL. However. the mounting posi—
`tion and forming method of the scan drivers SUV are not
`limited thereto. For exampie, the scan drivers SDV may
`be an integrated circuit (i0) chip and the lC chip may be
`provided in a chip on glass form on the substrate SUB.
`Aiternativeiy, the scan drivers SDV may be mounted on
`a printed circuit board to be connected to the substrate
`SUB through a connection member.

`iight emitting driver EDVi may also be disposed at the
`longitudinai part in the first peripheral region PPAi. The
`tirstiight emitting driver EDVi may hedi posed at r t least
`one side of the iongittidinai part of the first peripheral
`region PPAi. The first iight emitting driver EDVi may
`extend aiong the length direction of the first peripheral
`region PPA’l.

`in an embodiment of the presentdisclosure, the
`light emitting drivers EDV may be directiy mounted on
`the substrate SUB. When the light emitting drivers EDV
`are directly mounted on the substrate SUB, the light emit—
`ting driv are EDV may be formed together with the pixeis
`PXi.
`in the process of forming the pixels PXL. l-lovvever,
`the mounting position and forming method of the light
`em itting drivers EDV are not limited thereto. Forexampie,
`the iight er .itting drivers EDV may be an it? chip and the
`i0 chip may be provided in a chip on glass form on the
`substrate SUB. Alternatively, the light emitting drivers
`EDV may be mounted on a printed Circuit board to be
`connected to the substrate SUB through a connection
`member.
