Patent ID: 8487301

Claim:
An organic light-emitting display device comprising: a substrate; a thin-film transistor (TFT) on the substrate; a planarizing layer covering the TFT; a pixel electrode on the planarizing layer and electrically coupled to the TFT; a protective layer surrounding an edge of the pixel electrode; a pixel defining layer (PDL) having an overhang (OH) structure protruding more than a top surface of the protective layer, covering the protective layer and the edge of the pixel electrode, and exposing a portion of the pixel electrode surrounded by the protective layer; a counter electrode facing the pixel electrode; and an intermediate layer between the pixel electrode and the counter electrode and comprising a light-emitting layer and an organic layer, wherein the thickness of the intermediate layer is greater than the thickness of the protective layer, and wherein a portion of the intermediate layer extends into a gap between a portion of the PDL and a portion of the pixel electrode.
