Abstract
An organic EL element includes a transparent supporting substrate; a diffraction grating having a concavity and convexity layer with first concavities and convexities formed on a surface thereof, disposed on the transparent supporting substrate; and a transparent electrode, an organic layer having at least a light emitting layer, and a metal electrode having second concavities and convexities on a surface facing organic layer, which are stacked in this order on the diffraction grating and formed into such shapes such that a shape of the first concavities and convexities is maintained, wherein conditions (A), (B) and (C) respectively relating to a Fourier transformed, standard deviations pertaining to depth distributions for first and second concavities and convexities, and a ratio of the change in standard deviation of depth distribution of the second concavities and convexities relative to depth distributions of the first concavities and convexities are satisified.
