Abstract
The organic electroluminescent element includes: a substrate; a first electrode on a surface of the substrate; a second electrode opposite the first electrode; and a functional layer that is between the first electrode and the second electrode and includes at least a light emission layer. In this organic electroluminescent element, the first electrode is a metal electrode and also is a light-reflective electrode, the second electrode is a light-transmissive electrode, and thus light is allowed to emerge outside from the second electrode. The light emission layer is of a polymer material and has an in-plane direction and a thickness direction. A refractive index in the in-plane direction of the light emission layer is greater than a refractive index in the thickness direction of the light emission layer.
