Abstract: A flexible display device includes a cover member having a bending area and a non-bending area. The non-bending area is disposed on opposite sides of the bending area. The bending area is bent or folded about a bending axis. A display panel is disposed under both the bending area and the non-bending area of the cover member. The display panel has a smaller area than that of the cover member. An auxiliary member is disposed alongside the display panel, and under the bending area of the cover member, such that a width of the cover member is substantially equal to a width of the display panel plus a width of the auxiliary member.
