Abstract
The present invention is intended to provide an organic LED element in which the extraction efficiency is improved up to 80% of emitted light, and provides a translucent substrate comprising a translucent glass substrate; a scattering layer formed on the glass substrate and comprising a glass which contains a base material having a first refractive index for at least one wavelength of light to be transmitted and a plurality of scattering materials dispersed in the base material and having a second refractive index different from that of the base material; and a translucent electrode formed on the scattering layer and having a third refractive index higher than the first refractive index, wherein distribution of the scattering materials in the scattering layer decreases toward the translucent electrode.
