| Abstract | The present invention provides a highly efficient light-extrac tion layer and an organic electroluminescence element excel lent in light-extraction efficiency. The light-extraction layer of the present invention comprises a reflecting layer and a three-dimensional diffraction layer formed thereon. The dif fraction layer comprises fine particles having a variation coef ficient of the particle diameter of 10% or less and of a matrix having a refractive index different from that of the fine par ticles. The particles have a volume fraction of 50% or more based on the volume of the diffraction layer. The particles are arranged to form first areas having short-distance periodicity, and the first areas are disposed and adjacent to each other in random directions to form second areas. The organic elec troluminescence element of the present invention comprises the above light-extraction layer. |
