ORGANIC LIGHT-EMITTING DEVICE |
| 摘要 |
An organic light-emitting device comprising an anode (103); a cathode (109); a light-emitting layer (105) between the anode and the cathode; and an electron-transporting layer (107) comprising an electron-transporting material between the cathode and the light-emitting layer, wherein the cathode comprises a layer of a conducting material (109B) and a layer of an alkali metal compound (109A) between the electron-transporting layer and the layer of conducting material and wherein the electron-transporting material is a conjugated polymer comprising arylene repeat units. |
