| 摘要 |
An organic electroluminescence device having, between a pair of electrodes, at least a light-emitting layer, a first hole transport layer between the light-emitting layer and an anode, and a first electron transport layer between the light-emitting layer and a cathode, wherein the organic electroluminescence device has at least one of a second electron transport layer, which is disposed between the light-emitting layer and the first hole transport layer and adjacent to the light-emitting layer, or a second hole transport layer, which is disposed between the light-emitting layer and the first electron transport layer and adjacent to the light-emitting layer. An organic electroluminescence device having high emission efficiency and high driving durability is provided.
