ORGANIC ELECTROLUMINESCENT ELEMENT, AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2010/084816

A1

Disclosed is an organic electroluminescent element which can be produced by a wet process steadily, has high external quantum efficiency, and rarely undergoes coating unevenness.  Also disclosed is a method for producing the organic electroluminescent element.  Specifically disclosed is a method for producing an organic electroluminescent element by a wet process in which at least one layer is formed through the steps of coating a solution prepared by dissolving an organic material in a solvent and subsequently removing the solvent from a coating product by air blow, wherein the temperature of a coating solution, the temperature of a substrate and the temperature of a coating environment meet the requirement represented by the following formula: (the temperature of a coating environment) ≥ (the temperature of a coating solution) ≥ (the temperature of a substrate), the thickness of a liquid film formed is 1 to 100 μm, the rate of the air blow is 0.1 to 5 m/s, and the time between the completion of the coating and the initiation of the air blow is 0 to 60 seconds.
