Abstract
An objective is to provide a method of manufacturing an organic electroluminescence element possessing a thin film exhibiting relatively low film-strength formed via a continuous wet coating process. Disclosed is a method of manufacturing an organic electroluminescence element possessing a substrate film and provided thereon at least an organic layer placed between a pair of facing electrodes, possessing a light emitting layer containing an organic light emission material; possessing the steps of forming the organic layer on a first electrode provided on the substrate film by a continuous wet coating method; and cutting the substrate film with an upper cutting blade and a lower cutting blade, wherein the lower blade faces the substrate film, the upper blade has a blade edge angle of 30-60°, and the lower blade has a blade edge angle of 80-90°.
