METHOD FOR MANUFACTURING ORGANIC ELECTROLUMINESCENT ELEMENT, AND ORGANIC ELECTROLUMINESCENT ELEMENT

摘要

The purpose of the present invention is to provide: a method for manufacturing an organic electroluminescent element which has low driving voltage and long service life, while being free from emission unevenness; and an organic electroluminescent element which is manufactured by the manufacturing method. This method for manufacturing an organic electroluminescent element is a method for manufacturing an organic electroluminescent element that has a positive electrode and a negative electrode on a substrate, with at least three organic layers being interposed between the positive electrode and the negative electrode. This method for manufacturing an organic electroluminescent element is characterized in that at least one organic layer is formed through a step wherein a coating liquid for organic layers containing an organic layer-forming material and a solvent is applied over the substrate and then the organic layer is heated so that not less than 90% by mass of the solvent contained in the coating liquid for organic layers is removed within two seconds.
