1. An organic light-emitting display comprising:
a substrate having a through hole passing from a top surface of the substrate to a bottom surface of the substrate;
a plurality of light-emitting diodes arranged in a display area surrounding the through hole, the plurality of light-emitting diodes comprising a light-emitting diode, the light-emitting diode comprising:
a pixel electrode layer;
an opposite electrode layer facing the pixel electrode layer; and
an intermediate layer between the pixel electrode layer and the opposite electrode layer, the intermediate layer comprising an organic emission layer and a functional layer; and
a stepped portion in an intermediate area between the through hole and the display area, the stepped portion having an undercut structure,
wherein at least one of the functional layer or the opposite electrode layer extends toward the through hole and is disconnected by the stepped portion.
