ABSTRACT:
Provided is a white organic light emitting device comprising an anode, a cathode, and an organic layer formed between the anode and the cathode, wherein the organic layer comprises one green emissive layer, one blue emissive layer, one red emissive layer, and one charge generating layer formed between any two of the foregoing green, blue and red emissive layers. The white organic light emitting device has a tandem structure providing the simplest structure for the three color light emissions of green, blue and red.
