| 摘要 |
An organic electroluminescent element wherein the light extraction efficiency is improved without lowering the electrical conductivity or the transporting or blocking performance for electrons or holes in a transparent electrode or an organic layer. The organic electroluminescent element comprises, on a transparent substrate, at least a light-transmitting first electrode part, an organic light-emitting layer part and a second electrode part, in this order from the substrate, and is characterized in that the first electrode part contains at least metal nanowires and that the average refractive index of the first electrode part is lower than the average refractive index of the organic light-emitting layer part.
