Organic electroluminescence element
摘要:
An organic electroluminescence element comprising: a pair of electrodes, and a light emitting layer provided between the pair of electrodes, the layer comprising a light-emitting-layer material, a first dopant and a second dopant that satisfy the following relations, EV0>EV1 and EV0>EV2  (A) EC0≧EC2  (B) EG0>EG1 and EG0>EG2  (C) wherein EV0, EV1 and EV2 are the valence electron levels of the light-emitting-layer material, the first dopant and the second dopant, respectively; EC0 and EC2 are the conduction levels of the light-emitting-layer material and the second dopant, respectively; and EG0, EG1 and EG2 are the energy gaps of the light-emitting-layer material, the first dopant and the second dopant, respectively.
