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.
