Abstract:
1. An organic light emitting display device comprising: a plurality of sub-pixels formed on a substrate, wherein each sub-pixel having a light emission region and a non light emission region includes: a drive thin film transistor on the substrate at the non light emission region, a protective layer on the substrate including the drive thin film transistor, a color filter on the protective layer at the emission region, a planarizing layer on the protective layer including the color filter, a first drain contact hole in the protective layer and the planarizing layer to expose a drain electrode of the drive thin film transistor, a light compensating layer on the planarizing layer, the light compensating layer having a second drain contact hole which exposes the first drain contact hole and at least one dummy hole which exposes the planarizing layer, and 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 and including a first electrode, an organic light emitting layer, and a second electrode.
