Patent ID: 7776641

Claim:
A method for manufacturing an organic light emitting display device, the method comprising: forming a switching element and a silicon nitride layer over a substrate; patterning and removing a portion of the silicon nitride layer formed on a light emitting region; forming an overcoat layer on the silicon nitride layer, wherein a portion of the overcoat layer corresponding to the light emitting region has a thickness between about 1.1 μm and about 2.1 μm; forming a first electrode over the light emitting region, the first electrode being electrically connected to the switching element; forming an organic light emitting layer in the light emitting region; and forming a second electrode on the organic light emitting layer, wherein a light emitted from the organic light emitting layer exits to an exterior after passing through the overcoat layer and the substrate in the light emitting region where the silicon nitride layer is absent.
