Abstract: A display device includes a display module including a first non-folding area, a folding area, and a second non-folding area, which are arranged in a first direction, a cushion layer disposed under the display module, and a supporter disposed under the cushion layer. The folding area is disposed between the first and second non-folding areas. A groove that overlaps the folding area and extends in a second direction crossing the first direction is defined in the cushion layer.
