Abstract
A method of manufacturing an organic EL element having a corrugated structure, the organic EL element comprising a transparent supporting substrate, a transparent electrode, an organic layer, and a metal electrode, the method comprises the steps of: laminating on the transparent supporting substrate a curable-resin layer having concavity and convexity formed thereon in a periodic arrangement in a way that a curable resin is applied onto the transparent supporting substrate, the curable resin is then cured with a master block being pressed thereto, and thereafter the master block is detached; and obtaining an organic EL element by laminating on the curable-resin layer the transparent electrode, the organic layer, and the metal electrode individually so that a shape of the concavity and convexity formed on a surface of the curable-resin layer can be maintained.
