Abstract
An organic light emitting diode, including a first electrode; a first light emitting unit on the first electrode; a charge generating layer on the first light emitting unit, the charge generating layer including a plurality of organic layers; a second light emitting unit on the charge generating layer; and a second electrode on the second light emitting unit, the plurality of organic layers of the charge generating layer including a first organic layer and a second organic layer that are respectively adjacent to the first light emitting unit and the second light emitting unit; and a third organic layer between the first organic layer and the second organic layer, the first organic layer and the second organic layer being one of a p-type layer or a hole transport layer, and the third organic layer being the other of the p-type layer or the hole transport layer.
