Abstract: A display device includes an electronic panel, a window, an optical sheet, and a stress control member. The electronic panel includes a first non-bending area having a first area overlapping the optical sheet and a second area overlapping at least part of the recessed area, a bending area configured to be bent relative to the first non-bending area, and a second non-bending area extending from the bending area and movable to a position opposing the first non-bending area. The optical sheet is disposed between the electronic panel and the window and having a recessed area defined therein extending toward a center of the optical sheet. The stress control member overlaps with at least a portion of the second area, at least a portion of the bending area, and at least a portion of the second non-bending area, respectively.
