Abstract
In an organic electroluminescent device having a carrier transport layer and an emitting layer which are composed of an organic material provided between a hole injection electrode and an electron injection electrode, a dopant for transporting carriers is doped into the carrier transport layer and/or a dopant for transporting carriers or moving excitation energy is doped into the emitting
Claims5
An organic electroluminescent device having a carrier transport layer and an emitting layer which are composed of an organic material provided between a hole injection electrode and an electron injection electrode, wherein
- a first dopant having luminescent properties and a second dopant which assists the first dopant having luminescent properties to emit light are doped into said emitting layer, wherein said second dopant does not emit light.
