透光性基板、その製造方法、有機LED素子及びその製造方法
Document Type and Number:
Japanese Patent JP5195755
Kind Code:
B2
Abstract:
The present invention provides an organic LED element in which the extraction efficiency is improved up to 80% of emitted light. Further, the invention relates to an electrode-attached translucent substrate having a translucent substrate, a scattering layer formed on the translucent substrate and containing a base material having a first refractive index for at least one wavelength of wavelengths of emitted light of an organic LED element and a plurality of scattering materials positioned in the inside of 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 equal to or lower than the first refractive index, in which distribution of the scattering materials in the scattering layer decreases from the inside of the scattering layer toward the translucent electrode.
