Abstract: A display device includes a flexible substrate including a bending area corresponding to an area at which the display device is bent, and a first area and a second area which is spaced apart from the first area by the bending area, a display element unit disposed in the first area of the flexible substrate; and a buffer member disposed in the bending area of the flexible substrate. The buffer member in the bending area includes: a first buffer member having a first maximum thickness, and a second buffer member having a second maximum thickness which is smaller than the first maximum thickness. Among the first buffer member and the second member, the first buffer member disposed closer to the first area and the second member disposed closer to the second area.

Abstract: A display device includes a display panel including a main area, a bending area at which the display panel is bendable, and a sub area, in order. The main area includes a display area and a non-display area which is adjacent to the display area. The bending area connects the sub area to the main area at the non-display area thereof, and is recessed from outer side surfaces of the main area and the sub area, to define a recess portion of the display panel at the bending area.
