Abstract:
The present application relates to a method for fabricating an organic light emitting display device, comprising: forming a drive thin film transistor on a substrate at a non-light emission region; forming a protective layer on the substrate; forming a color filter on the protective layer; forming a planarizing layer on a protective layer including the color filter; selectively removing the protective layer and the light compensating layer to form a first drain contact hole which exposes a drain electrode of the drive thin film transistor; forming a light compensating layer on the planarizing layer to have a second drain contact hole which exposes the first contact hole, and a dummy hole to expose the planarizing layer; and forming an organic light emitting element on the light compensating layer to be in contact with the drain electrode through the first and second drain contact holes.
