Abstract: A display device includes a substrate and a protection film disposed on a rear side of the substrate. The substrate includes a first portion including a display area and having a first width, and a second portion extending from the first portion and having a second width narrower than the first width. The protection film includes a cavity at a border portion of the first portion and the second portion of the substrate.
