Abstract: A display device includes a display module which is foldable and includes a first non-folding area, a folding area and a second non-folding area, in order, a first plate corresponding to the first non-folding area, a second plate corresponding to the second non-folding area and spaced apart from the first plate, and a cover film facing the display module with both the first plate and the second plate therebetween. The cover film includes a first film corresponding to each of the first non-folding area, the folding area and the second non-folding area, the first film attached to each of the first and second plates, and at the folding area, a second film attached to the first film. The display module which is folded disposes the second film between the first film and the first plate and between the first film and the second plate.

Abstract: A display device includes a display module, and a window which is disposed on the display module and in which a first non-folding region, a folding region, and a second non-folding region are sequentially defined in a first direction, wherein the window includes a base layer, a first hard coating layer disposed on an upper surface of the base layer, and a second hard coating layer disposed on a lower surface of the base layer, and the second hard coating layer includes a first portion overlapping the first non-folding region and the second non-folding region of the window, and a second portion overlapping the folding region of the window and having a hardness lower than a hardness of the first portion. Therefore, it is possible to provide a display device having desired surface hardness, impact resistance, and bending properties.
