Document Type and Number:
WIPO Patent Application WO/2021/060024
Kind Code:
A1
Abstract:
The problem to be solved by the present invention is to provide a method for manufacturing, via a simple process, an organic electroluminescent element in which brightness irregularities are ameliorated, and an organic electroluminescent element manufactured via said manufacturing method. The organic electroluminescent element manufacturing method according to the present invention is a method for manufacturing an organic electroluminescent element comprising: an anode; an organic functional layer including at least one light-emitting layer; and a cathode on a substrate, the method being characterized by comprising a step for forming the light-emitting layer via a wet process, and a heating/melting step for continuously or discontinuously altering, in the through-thickness direction of the light-emitting layer, the compositions of a host compound and a light-emitting dopant contained in the light-emitting layer.
