SUBSTRATE FOR ORGANIC ELECTRONIC DEVICE

摘要

PURPOSE: A substrate for an organic electronic device is provided to improve external quantum efficiency. CONSTITUTION: A high refractive layer (102) is formed on a base material layer (101). The refractive index of the high refractive layer is 1.8 to 2.5. The high refractive layer includes binders and scattering particles. The refractive index of the binders is 1.4 or more. The refractive index of the scattering particles is greater than 2.5.
