Abstract: The present disclosure relates to an organic light emitting diode and an organic light emitting device including thereof. The organic light emitting diode (OLED) includes multiple emitting parts disposed between two facing electrodes and at least one charge generation layer disposed between the multiple emitting parts. The at least one of the multiple emitting parts includes a green emitting material layer, and an energy bandgap between HOMO energy level of host and LUMO energy level of dopant in a P-type charge generation layer is controlled. The OLED and the organic light emitting device can improve their luminous efficiency by controlling charge injections in an emissive layer and improve efficiently white balance by suitable color compensation.
