| 摘要 |
An organic electroluminescent element includes a first electrode, an organic compound film including a plurality of layers that include an emissive layer, a second electrode, a protective layer, and a buffer layer formed by an evaporation method between the second electrode and the protective layer, light emitted from the emissive layer emerging from the second electrode side, in which the second electrode is formed of a metal film having a thickness of 5 nm to 20 nm, a distance between a surface of the emissive layer adjacent to the first electrode and a surface of the second electrode adjacent to the organic compound film is in the range of 55 nm to 90 nm, and the protective layer is formed by a sputtering method or a plasma-enhanced chemical vapor deposition method. |
