METHOD OF PREPARING ORGANIC ELECTROLUMINESCENT ELEMENT AND ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

Provided is a method of preparing an organic electroluminescent element. The method includes: a roughening step of roughening a surface of a moisture-proof substrate; a composite substrate-forming step of placing a resin film on the roughened surface of the moisture-proof substrate to form a composite substrate; an electroluminescent laminate-forming step of forming an organic electroluminescent laminate on a surface of the composite substrate; and a covering step of covering the organic electroluminescent laminate with a covering substrate that is larger than the resin film in a plan view. It gives a highly reliable organic electroluminescent element superior in light-outcoupling efficiency that is effectively resistant to water penetration and to degradation.
