Abstract: A display device comprises: a display panel; a window; and a first pressure sensor. The display panel comprises: a planar portion; a first curved portion connected to one side of the planar portion; and a first side portion connected to one side of the first curved portion. The window is on the display panel. The first pressure sensor overlaps with the first side portion. Here, the first side portion is in a plane different from each of the planar portion and the first curved portion.
