| 摘要 |
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 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, 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 a bottom surface on the transparent substrate side, an upper surface on the first electrode side and side surfaces, and each of the side surfaces of the light scattering layer has a surface tilted at an angle larger than right angle from the upper surface toward the bottom surface; and the first electrode is placed so as to continuously cover the side surfaces of the light scattering layer. |
