Organic electroluminescent element having a nanoostructure between a transparent substrate and an electrode

摘要

An organic EL element with high luminous efficiency is manufactured by fabricating a compound substrate by forming a microscopic unevenness on a transparent substrate of glass or the like using a sol-gel material and a nanoimprinting method, applying a high refractive index material on the microscopic unevenness, and planarizing the surface, and layering a first electrode, an organic solid layer including an organic light-emitting material and a first electrode in that order on the compound substrate.
