ORGANIC ELECTROLUMINESCENCE ELEMENT AND ILLUMINATION DEVICE |
| 摘要 |
The organic electroluminescence element includes: a positive electrode; a negative electrode; a plurality of light emitting layers interposed between the positive electrode and the negative electrode; and an interlayer-provided between the plurality of light emitting layers. The interlayer includes: a first layer-containing a nitrogen-containing heterocyclic compound; an alkali metal layer containing an alkali metal; a second layer containing a nitrogen-containing heterocyclic compound; and a hole injection layer containing an electron-accepting organic material. The first layer, the alkali metal layer, the second layer, and the hole injection layer are arranged in this order from the positive electrode to the negative electrode. The second layer is thicker than the alkali metal layer. |
