Abstract: An organic light emitting device including an organic light emitting element having a low driving voltage and a high luminous efficiency is provided. The organic light emitting device includes two or more stack emission units, and a charge generating layer including an N-type charge generating layer and a P-type charge generating layer is disposed between the stack emission units. Herein, the P-type charge generating layer is formed of a material having an LUMO energy level similar to an HOMO energy level of a hole transporting layer injected with holes from the P-type charge generating layer. Accordingly, even if the P-type charge generating layer is not additionally doped with a P-type dopant, it is possible to readily inject holes into a stack emission unit adjacent to the P-type charge generating layer.
