Patent ID: 8716058

Claim:
A method of manufacturing an organic light-emitting display device, the method comprising: (a) providing a substrate having at least one thin-film transistor (TFT); (b) sequentially forming a pixel electrode electrically coupling the TFT and a protective layer on the substrate; (c) forming a pixel defining layer (PDL) to surround an edge of the protective layer and to expose a portion of the protective layer by forming an insulation layer to cover the pixel electrode and the protective layer and patterning the insulation layer; (d) etching the protective layer to expose a portion of the pixel electrode, so that an overhang (OH) structure, in which the PDL protrudes more than the top surface of the protective layer, is formed; and (e) forming an intermediate layer by ejecting a light-emitting layer and at least one organic layer as liquid onto the exposed pixel electrode.
