ORGANIC EL ELEMENT AND ORGANIC EL DISPLAY PANEL |
| 摘要 |
An organic electroluminescence (EL) element including an anode, a light-emitting layer above the anode, a first functional layer on and in contact with the light-emitting layer, a second functional layer on and in contact with the first functional layer, and a cathode above the second functional layer. A lowest unoccupied molecular orbital (LUMO) level of the first functional layer is lower than at least one of a LUMO level of the second functional layer and a Fermi level of a metal material included in the second functional layer. |

1. An organic electroluminescence (EL) element comprising:
an anode; a light-emitting layer disposed above the anode; a first functional layer disposed on and in contact with the light-emitting layer; a second functional layer disposed on and in contact with the first functional layer; and a cathode disposed above the second functional layer, wherein a lowest unoccupied molecular orbital (LUMO) level of the first functional layer is lower than at least one of a LUMO level of the second functional layer and a Fermi level of a metal material included in the second functional layer. |
