摘要： An organic device includes a reflective film arranged on a substrate, a plurality of lower electrodes arranged above the reflective film, an organic function film configured to cover the plurality of lower electrodes, and an upper electrode arranged on the organic function film. A potential difference between the upper electrode and the reflective film is lower than a threshold voltage at which the organic function film operates.

摘要： An organic electroluminescent element includes a first electrode, a second electrode, and an organic compound layer disposed between the first and second electrodes. A protective layer and a planarization layer are disposed in this order on the light emission side of whichever of the first and second electrodes is closer to the light emission side. A surface of the protective layer adjacent to the planarization layer has an uneven shape. The planarization layer is in contact with the protective layer. A surface of the planarization layer away from the protective layer is flat. The refractive index of the planarization layer is equal to or lower than that of the protective layer and equal to or higher than that of a light emission medium in contact with the planarization layer.
