Method of manufacturing a light extraction substrate for an electroluminescent device

摘要

A light extraction substrate for an electroluminescent device and a manufacturing method thereof, in which light extraction efficiency is increased. The light extraction substrate for an electroluminescent device includes a substrate (11) and a light extraction layer (100) formed on the substrate. The light extraction layer contains an oxide that has a wide band gap of 2.8eV or more. The light extraction layer has a texture on the surface thereof.
