Disclosed is a white organic light emitting device (200; 300; 400; 800). The white organic light emitting device includes a first emission part (210; 310; 410; 810) between a first electrode (202; 302; 402; 802) and a second electrode (204; 304; 404; 804), a second emission part (220; 320; 420; 820) on the first emission part, and a third emission part (230; 330; 430; 830) on the second emission part. At least one of the first to third emission parts includes at least two emission layers (214, 215; 334, 335; 434, 435; 814, 815) including a red emission layer (215; 334; 434; 815), 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. |
