According to one embodiment, an organic electroluminescence device includes a first electrode, a second electrode, a first organic layer and a second organic layer. The second electrode includes a metal. The first organic layer is provided between the first electrode and the second electrode. The first organic layer is configured to emit light. The second organic layer is provided between the first organic layer and the second electrode. A refractive index of the second organic layer in a thickness direction for the light is lower than a refractive index of the first organic layer for the light. |
