A display device includes a display panel, a cushion layer below the display panel, a heat-dissipation sheet below the cushion layer, and a flexible circuit substrate electrically connected to the display panel and bent toward a rear surface of the display panel. The display panel includes a first region that overlaps the flexible circuit substrate and a second region that overlap the cushion layer in a direction perpendicular to the rear surface. The cushion layer and the heat-dissipation sheet only overlap the second region in a direction perpendicular to the rear surface.
