Abstract: A display device includes: a display panel including a flat area and a bending area positioned adjacent to the flat area, a panel bottom sheet arranged under the display panel and overlapping with the flat area and the bending area, and a panel-sheet coupling layer between the display panel and the panel bottom sheet and including a first panel-sheet coupling part arranged across the flat area and the bending area, and a second panel-sheet coupling part overlapping with the bending area and extended continuously along a side of the first panel-sheet coupling part, a thickness of the panel-sheet coupling layer becoming smaller from a central portion of the bending area toward a side portion of the bending area, and the panel bottom sheet having a curved shape that is gentler than a curved shape of the display panel.
