A display device includes a display panel including: a bending area at which the display panel is bent with reference to a bending axis, and a non-bending area at which the display panel is not bent and at which an image is displayed; and a support member on which is supported the display panel, defining: a recessed portion disposed in the bending area; first and second bumps spaced apart from each other to define the recessed portion therebetween; and extensions extended from the first and second bumps, in a direction away from the recessed portion, to opposing ends of the support member, respectively. In cross-section, a size of the first bump is different from a size of the second bump.
