Abstract:
A light extracting member for an organic electroluminescent element, to be provided on a side for extracting light emitted by the organic electroluminescent element, wherein a light extracting surface of the member has a concave-convex structure which is configured such that when comparing an intensity of light that enters the member and is output from the light extracting surface with an intensity of light that is output from a flat light extracting surface of a virtual member, a frontal intensity and an integrated intensity of the former are each greater by a factor of 1.3 or more.
