`
`15
`
`
`
`to the first direction.
`
`14.
`
`The display device of claim 9, wherein a surface of the rotation belt that is
`
`parallel to the first direction isflat.
`
`15.
`
`The display device of claim 14, wherein a width of the surface of the rotation
`
`belt parallel to the first direction is greater than a thickness of the rotation belt measured in a
`
`direction perpendicularto the first direction.
`
`16.
`
`The display device of claim 9, wherein
`
`groove portions or convex portions are disposed on a surface of thefirst roller and a
`
`surface of the second roller, and
