Abstract
An organic light-emitting display device including a substrate; at least one thin-film transistor (TFT) formed on the substrate; a planarizing layer covering the TFT; a pixel electrode, which is formed on the planarizing layer and is connected to the TFT; a protective layer surrounding an edge of the pixel electrode; a pixel defining layer (PDL), which has an overhang (OH) structure protruding more than the top surface of the protective layer, covers the protective layer and the edge of the pixel electrode, and exposes a portion of the pixel electrode surrounded by the protective layer; a counter electrode facing the pixel electrode; and an intermediate layer, which is interposed between the pixel electrode and the counter electrode and includes a light-emitting layer and at least one organic layer, where the thickness of the intermediate layer is greater than the thickness of the protective layer.
