ORGANIC LIGHT EMITTING DISPLAY DEVICE AND METHOD FOR FABRICATING THE SAME

摘要

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.

1. A method for fabricating an organic light emitting display device having a plurality of sub-pixels, each sub-pixel having a light emission region and a non-light emission region, the method comprising the steps of:
forming a drive thin film transistor on a substrate at non-light emission region; forming a protective layer on the substrate including the drive thin film transistor; forming a color filter on the protective layer; forming a planarizing layer on the 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 at least one 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.
