ORGANIC ELECTROLUMINESCENT ELEMENT AND LIGHT EMITTING DEVICE |
| 摘要 |
According to one embodiment, an organic electroluminescent element includes a first electrode, a reflective layer, an organic light emitting layer, a second electrode, and an optical buffer layer. The reflective layer is provided to face the first electrode. The organic light emitting layer is provided between the first electrode and the reflective layer. The second electrode is provided between the organic light emitting layer and the reflective layer. The optical buffer layer is provided between the second electrode and the reflective layer. The refractive index of the optical buffer layer is lower than a refractive index of the organic light emitting layer. The optical buffer layer includes a gas filled between the second electrode and the reflective layer. |
