ORGANIC EL ELEMENT |
| 摘要 |
An organic electroluminescence (EL) element including an anode, a cathode opposing the anode, a light-emitting layer between the anode and the cathode, a hole transport layer in contact with the light-emitting layer, between the light-emitting layer and the anode, and an electron transport layer in contact with the light-emitting layer, between the light-emitting layer and the cathode. A difference between a lowest unoccupied molecular orbital (LUMO) level of an organic material included in the light-emitting layer and a LUMO level of an organic material included in the electron transport layer is greater than a difference between a highest occupied molecular orbital (HOMO) level of an organic material included in the hole transport layer and a HOMO level of the organic material included in the light-emitting layer. |

1. An organic electroluminescence (EL) element comprising:
an anode; a cathode opposing the anode; a light-emitting layer disposed between the anode and the cathode; a hole transport layer in contact with the light-emitting layer, disposed between the light-emitting layer and the anode; and an electron transport layer in contact with the light-emitting layer, disposed between the light-emitting layer and the cathode, wherein a difference between a lowest unoccupied molecular orbital (LUMO) level of an organic material included in the light-emitting layer and a LUMO level of an organic material included in the electron transport layer is greater than a difference between a highest occupied molecular orbital (HOMO) level of an organic material included in the hole transport layer and a HOMO level of the organic material included in the light-emitting layer. |
