    摘要： Disclosed is a white organic light emitting device in which a lifetime of a device is enhanced. The white organic light emitting device includes a first emission part between a first electrode and a second electrode, and a second emission part on the first emission part. At least one among the first and second emission parts includes an emission area control layer. 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 among the first to third emission parts includes an emission area control layer.
