`[Embodiments]
`(Embodiment 1) FIG. 1 is a schematic view illustrating a
`display device according to a first embodiment of the present
`invention. As shown in the drawing, this device is installed in
`a vehicle carriage 03, and comprises a plurality of displays 01,
`and a drive device (02 or the like) that stores image data and
`performs display on the displays on the basis thereof. Flat
`displays, having shapes conforming to the shape of the
`region in which the displays are to be installed within the
`vehicle carriage 03, are used as the displays 01.

`
`the display is to be installed within the vehicle are used as the
`displays.
`[0006] The drive device stores image data, which it searches
`for and delivers, and has a memory/search device such as an
`image information data searching device using various types
`of optical/magnetic recording media such as optical discs and
`hard discs, and rapidly displays images on the displays, on
`the basis of this image data.
`[0007] If the vehicle has a transparent glass part, the display
`may constitute part of this transparent glass part, or be
`installed in this transparent glass part itself.
`[0008] The drive device may change the display content of
`the display
`in approximate synchronization with
`the
`movement or stopping of the vehicle. Further, the displays
`may be arranged adjacent to each other, and the drive device
`may perform display so as to change the display content on
`each display or so that the display content continuously
`moves across adjacent displays. Furthermore, a means for
`detecting a movement position of the vehicle may be
`provided, wherein the drive device changes the display
`content on the display in accordance with a detection signal
`from this detection means. Furthermore, if the vehicle has a
`door for shielding from the exterior, the drive device may
`change the display content on the display in approximate
`synchronization with opening and closing of this shielding
`door. Further, the drive device may have a means for
`transferring the image data to the displays, which accesses
`the stored image data in accordance with the vehicle
`movement or position, or the opening and closing of the door,
`and transfers the image data to the displays.
`[0009] The display device may comprise a means for
`detecting changes in brightness in part of the vehicle, and the
`display may comprise a backlight, the brightness of which
`changes in accordance with the output of this detection
`means.

`memory search online transfer means provided within the
`vehicle, which stores image data, and accesses and transfers
`the same, and a communication information transfer means,
`which receives image data that is transmitted from outside
`the vehicle, wherein display is performed on the displays on
`the basis of image data from this information memory search
`online transfer means and this communication information
`transfer means.
`[0011] This may have a pair of displays that are installed with
`their backs facing each other and forming a certain angle, or
`may have a pair of displays that are installed with their backs
`facing each other, while this pair of displays has a mutually
`shared backlight.
`[0012] If the display comprises a backlight, the display device
`may comprise a means for supplying a cooling air flow that
`cools this backlight via a gap between the display and the
`inner wall of the vehicle. Furthermore, this may comprise a
`means for discharging this cooled air to the exterior of the
`vehicle.
`[0013] The display may be a surface-stabilized ferroelectric
`liquid crystal display, to which voltage is applied only when
`the display content changes and which otherwise maintains
`the display content without the application of voltage.
`Furthermore, display may be performed by selecting and
`combining displays from nematic liquid crystal displays, thin
`liquid crystal displays, surface-stabilized
`film
`transistor
