Abstract
An organic light emitting display device and a method for manufacturing the same are disclosed. The method for manufacturing the organic light emitting display device includes 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 through which light is transmitted, forming an overcoat layer formed on the silicon nitride layer, wherein a portion of the overcoat layer corresponding to the light emitting region has a thickness of about 1.1 μm to about 2.1 μm, forming a first electrode electrically connected to the switching element over the light emitting region, and sequentially forming an organic light emitting layer and a second electrode on the first electrode.
