Beschreibung
Zusammenfassung:An organic electroluminescence device of an embodiment includes a first electrode, a second electrode, and an emission layer disposed between the first electrode and the second electrode, wherein the emission layer includes a host having a first luminescent onset wavelength, a first dopant having a second luminescent onset wavelength, and a second dopant different from the first dopant and having a third luminescent onset wavelength. The third luminescent onset wavelength is greater than each of the first luminescent onset wavelength and the second luminescent onset wavelength, and the device has improved emission efficiency and/or long-lifespan characteristics.
