Abstract: Disclosed is a white organic light emitting device. The white organic light emitting device includes a first emission part between a first electrode and a second electrode, a second emission part on the first emission part, and a third emission part on the second emission part. At least one of the first to third emission parts includes at least two emission layers including a red emission layer, and a position of the red emission layer is set to enhance a color reproduction rate and at least one of red efficiency, green efficiency, and blue efficiency.

Abstract: A white light emitting device, or more particularly an inverted white light emitting device, includes a plurality of stacks configured to emit white light, and an optical compensation layer provided at an outer surface of an electrode through which light is emitted to the outside. The configuration reduces the thickness of an electron transport layer adjacent to a cathode in the stack and therefore reduces the driving voltage and improves the viewing angle characteristics and as well as the efficiency.
