Abstract
A method of manufacturing an organic electroluminescent device includes 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 and dispersing a forming material of a functional layer forming at least a portion of an organic electroluminescent element in a solvent; and drying the coated liquid composition so as to form the functional layer. In the coating of a liquid composition, a fluorine group-containing solvent which contains a fluorine group is used as a solvent.
