Abstract:
1. An organic light-emitting display device comprising: a substrate; a plurality of pixels on the substrate; a plurality of first electrodes, each first electrode disposed in each pixel of the plurality of pixels and contacting a planarization layer; a pixel defining layer comprising a first pixel defining sub-layer disposed between each two adjacent first electrodes, and a second pixel defining sub-layer covering the first pixel defining sub-layer and surface edge portions of each two adjacent first electrodes, wherein the first pixel defining sub-layer contacts the planarization layer and wherein the second pixel defining sub-layer comprises an opening in a center of the second pixel defining sub-layer; an intermediate layer disposed on each of the first electrodes and comprising an emission layer; and a second electrode configured to face the plurality of first electrodes wherein the second electrode contacts the first pixel defining sub-layer through the opening, and the second electrode has a substantially uniform thickness.
