Abstract
The present disclosure relates to an organic light emitting diode (OLED) including plural light emitting material layers disposed between two electrodes and an electron blocking layer, wherein an energy level of the electron blocking layer disposed adjacently to an emitting material layer with relatively low level delayed fluorescent material and an energy level of the delayed fluorescent material are controlled, and an organic light emitting device having the diode. The OLED can lower its driving voltage and maximize its luminous efficiency and luminous lifetime.
