| Zusammenfassung: | The present disclosure relates to an organic light emitting diode (OLED) where an emissive layer comprises four emitting parts each of which is sequentially disposed between a first electrode and a second electrode; and charge generation layers each of which is disposed between emitting parts, where one emitting part comprises a red emitting material layer and a blue emitting material layer comprising a blue emitter and a host having a high HOMO and/or a LUMO energy levels. The OLED may implement efficient white emission by improving the blue emission intensity and/or blue temperature. |
