Abstract
The present invention provides an organic LED element having the significantly larger light emission area than conventional ones. The invention relates to an organic LED element, comprising: a transparent substrate; a light scattering layer; a transparent first electrode; an organic light-emitting layer; and a second electrode formed in this order, wherein the light scattering layer has a base material comprising a glass, and a plurality of scattering materials dispersed in the base material; the light scattering layer has side surfaces, and each of the side surfaces has a surface tilted at an angle larger than right angle from an upper surface on the first electrode side toward a bottom surface on the transparent substrate side; and the first electrode is placed so as to continuously cover the side surfaces.
