Abstract:
The present invention relates to a method for producing an organic electroluminescence element, comprising an organic layer between an anode and a cathode of the organic electroluminescence element by a wet film-forming method by using a composition containing an organic electroluminescence element material and a solvent in any one environment of the following film formation environments 1 to 3, and drying the formed film: film formation environment 1: a carbon dioxide concentration of 0.7 g/m3 or less and an oxygen concentration of 18 to 22 vol %, film formation environment 2: a sulfur oxide concentration of 2.2 μg/m3 or less and an oxygen concentration of 18 to 22 vol %, and film formation environment 3: a nitrogen oxide concentration of 3.1 μg/m3 or less and an oxygen concentration of 18 to 22 vol %.
