Abstract: A display device includes: a display panel comprising a folding region configured to be folded around a folding axis and a non-folding region adjacent to the folding region; and a window on the display panel and configured to be folded with the display panel, wherein: a side surface of the display panel has a first surface roughness in the folding region and a second surface roughness in the non-folding region; the first surface roughness is lower than the second surface roughness; and a side surface of the window has the same surface roughness in the non-folding region and the folding region.

Abstract: A worktable for laser processing includes a lower plate, internal blocks, and external blocks. The lower plate includes a first area, a second area surrounding the first area, and a third area surrounding the second area. The internal blocks are disposed on the lower plate in the first area and the external blocks are disposed on the lower plate in the third area. The external blocks surround the internal blocks.

Abstract: A display device includes a display module and a support plate disposed on the display module and including a plurality of first fibers and a plurality of second fibers disposed on the first fibers and extending to cross the first fibers in a plan view. An opening is defined in the support plate and includes first sides parallel to an extension direction of the first fibers and facing each other and second sides parallel to an extension direction of the second fibers and facing each other.
