ORGANIC ELECTROLUMINESCENCE DEVICE |
| 摘要 |
An organic electroluminescence device includes an anode, a hole transport layer on the anode, the hole transport layer including a plurality of layers having different compounds as main components, an emission layer on the hole transport layer, and a cathode on the emission layer. A hole mobility of a first layer of the hole transport layer having the greatest thickness among the plurality of layers of the hole transport layer is greater than a hole mobility of at least one layer of the hole transport layer between the first layer of the hole transport layer and the emission layer. |

1. An organic electroluminescence (EL) device, comprising:
an anode; a hole transport layer on the anode, the hole transport layer including a plurality of layers having different compounds as main components; an emission layer on the hole transport layer; and a cathode on the emission layer, wherein a hole mobility of a first layer of the hole transport layer having the greatest thickness among the plurality of layers of the hole transport layer is greater than a hole mobility of at least one layer of the hole transport layer between the first layer of the hole transport layer and the emission layer. |
