Abstract: Discussed is a white organic light emitting device for enhancing emission efficiency and panel efficiency. The white organic light emitting device can include a first emission part between a first electrode and a second electrode and configured to include a first emission layer (EML), a second emission part on the first emission part and configured to include a second EML, and a third emission part on the second emission part and configured to include a third EML. The first to third emission parts have an emission position of emitting layers (EPEL) structure in which the first to third emission parts have a maximum emission range in respective emission areas of the first to third EMLs.
