ABSTRACT:
A white organic light emitting device includes: an anode formed on a substrate; a first emissive layer, in which a first sub-emissive layer and a second sub-emissive layer are stacked, formed on the substrate; a second emissive layer, in which a third sub-emissive layer and a fourth sub-emissive layer are stacked, formed on the first emissive layer; a first intermediate layer supplying electrons to the first emissive layer and a second intermediate layer supplying holes to the second emissive layer, wherein the first and second intermediate layers are formed between the first emissive layer and the second emissive layer; and a cathode formed on the second emissive layer.
