Abstract:
1. A method of manufacturing an organic electroluminescence element comprising a substrate film and provided thereon at least an organic layer placed between a pair of facing electrodes, the organic layer comprising a light emitting layer containing an organic light emission material; the method comprising 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 organic electroluminescence element with an upper cutting blade and a lower cutting blade, wherein the upper cutting blade opposes the lower cutting blade, and the lower blade faces the substrate film, wherein the upper blade has a blade edge angle of 30-60°, wherein the lower blade has a blade edge angle of 80-90°, wherein the upper cutting blade and the lower cutting blade each have a surface roughness of 0.1 s or less, wherein a total thickness of the at least an organic layer and the pair of facing electrodes is 1 μm or less, wherein the upper cutting blade and the lower cutting blade each have a clearance of 80 μm or less, and wherein each of the upper cutting blade and the lower cutting blade with the substrate film had a dynamic friction coefficient of 0.2 or less.
