ORGANIC LED ELEMENT, TRANSLUCENT SUBSTRATE, AND METHOD FOR MANUFACTURING ORGANIC LED ELEMENT

摘要

Disclosed is an organic LED element having a significantly large light emitting area compared with conventional organic LED elements. The organic LED element has: a transparent substrate; a light scattering layer formed on the transparent substrate; a transparent first electrode formed on the light scattering layer; an organic light emitting layer formed on the first electrode; and a second electrode formed on the organic light emitting layer. The light scattering layer has a base material composed of a glass, and a plurality of pieces of scattering material scattered in the base material. The light scattering layer has a bottom surface on the transparent substrate side, the upper surface on the first electrode side, and side surfaces. Each of the side surfaces of the light scattering layer has a surface tilted at an angle smaller than right angle from the upper surface toward the bottom surface, and the first electrode is disposed such that the first electrode continuously covers the side surfaces of the light scattering layer.
