Patent ID: 8173485

Claim:
A method of manufacturing an organic light emitting device, the method comprising: forming a first electrode on a substrate; forming a photoresist layer to cover the first electrode; patterning the photoresist layer and forming a blocking layer on and contacting a first side of the first electrode opposite to a second side of the first electrode that faces the substrate; forming a pixel defining layer on the substrate to cover side ends of the first electrode, wherein after forming the pixel defining layer, at least a portion of a side of the blocking layer extending from the first side of the first electrode is exposed, and a thickness of a thickest portion of the pixel defining layer is less than a total thickness of the first electrode and the blocking layer; removing the blocking layer and exposing the first side of the first electrode while the side ends of the first electrode remain covered by the pixel defining layer; forming an intermediate layer comprising an organic light emitting layer on the first side of the first electrode that is exposed by removing the blocking layer; and forming a second electrode on the intermediate layer.
