SUBSTRATE FOR AN ORGANIC ELECTRONIC ELEMENT AND A PRODUCTION METHOD THEREFOR

摘要

The present invention relates to a substrate for an organic electronic element and makes it possible to reduce surface resistance and improve light-extraction efficiency, the substrate comprising: a base material; a scattering layer which is formed on the base material and comprises an electrically-conductive pattern for reducing the surface resistance of an electrode, scattering particles for scattering light and a binder, and which forms an uneven structure in the surface opposite the base material; and a flattening layer which is formed on the scattering layer and flattens the surface undulations caused by the uneven structure of the scattering layer, wherein the refractive index (Na) of the scattering particles and the refractive index (Nb) of the flattening layer satisfy the relationship in formula 1 below. [Formula 1] |Na-Nb|=0.3. In the formula, Na signifies the refractive index of the scattering particles and Nb signifies the refractive index of the flattening layer.
