Organic electroluminescent display device

Abstract

An organic electroluminescent display device is disclosed which includes: a lower substrate including a first substrate defined into red, green and blue sub-pixel regions, first and second switching elements formed in the red and green sub-pixel regions, first and second anodes each connected to the first and second switching elements, and a first organic light emission layer entirely formed on the first substrate provided with the first and second anodes; and an upper substrate including a second substrate, red and green color filter layers formed on the second substrate corresponding to the red and green sub-pixel regions, a third switching element formed on the second substrate corresponding to the blue sub-pixel region, a third anode connected to the third switching element, and a second organic light emission layer entirely formed on the second substrate provided with the red and green color filter layers and the third anode.

Dependencies are inferred from the claim text.
