Abstract:
1. An organic electroluminescent element comprising a transparent substrate and provided thereon, at least a first electrode section with a light transmission property, an organic light emission layer section and a second electrode section in that order, the first electrode section containing at least metal nanowires, wherein an average refractive index of the first electrode section is lower than that of the organic light emission layer section; wherein when the first electrode section is divided in a first electrode part and a second electrode part having the same thickness, the first electrode part being close to the organic light emission layer section and the second electrode part close to the transparent substrate, the following formula is satisfied: wherein N1el represents an average refractive index of the first electrode part; and N1s represents an average refractive index of the second electrode part.
