摘要 |
To provide a process of producing an organic electroluminescence element having a high current efficiency and a long drive life by a wet film formation process. The present invention relates to a process of producing an organic electroluminescence element composition, comprising a filtration step of filtering a solution containing an organic electroluminescence element material and a solvent, wherein the composition is obtained after a time-elapsing step wherein 8 hours or more elapses after the filtration step, and the composition is used for a wet film formation of an organic layer in an organic electroluminescence element.
