Abstract:
1. A method of manufacturing an organic electroluminescent device comprising: forming partition walls partitioning pixels on a substrate; subjecting a surface of each of the partition walls to a lyophobic treatment; coating a liquid composition on each of regions surrounded by the partition walls, the liquid composition obtained by dissolving or dispersing a forming material of a functional layer forming at least a portion of an organic electroluminescent element in a solvent that does not contain a fluorine group-containing solvent; drying the coated liquid composition so as to form the functional layer by means of vacuum drying; dissolving the functional layer with a solvent containing the fluorine group-containing solvent, the solvent being a liquid solvent that contacts the functional layer; and drying the dissolved functional layer to form the functional layer by means of the vacuum drying again, wherein the fluorine group-containing solvent includes at least one of fluorobenzene, fluorotoluene, benzotrifluoride, bis(4-fluorophenyl)ether, fluoroxylene, 4-fluoro-α-methylstyrene, 1-(4-fluoro-1-methylphenyl)-3,3,5-5-tetramethyl-cyclohexane, fluoroaniline, and fluoroanisole.
