1. A flexible organic light-emitting display apparatus comprising:
a substrate comprising a first area including a plurality of pixels, a bending area that is bent and extends from one side of the first area, and a second area that extends from one side of the bending area and faces at least a portion of the first area; and
a backplate on a rear of the substrate and in contact with the rear of the substrate, the backplate comprising a bending structure that reduces stress applied to the bending area of the substrate and repulsive force while the bending area of the substrate is bent,
wherein the bending structure comprises a plurality of slit patterns formed to penetrate the backplate by partially removing a material forming the backplate.
