Abstract:
An organic light-emitting display device includes: a substrate; an insulating layer disposed on the substrate; a first electrode disposed on the insulating layer; a pixel defining layer disposed on the first electrode and defining an emission area by an opening that exposes at least part of the first electrode; a metal layer disposed on the pixel defining layer and in a non-emission area around the emission area; an organic light-emitting layer disposed on the first electrode in the opening; and a second electrode disposed on the organic light-emitting layer in the emission area and the non-emission area, where the metal layer is disposed between the pixel defining layer and the second electrode in the non-emission area.
