PROBLEM TO BE SOLVED: To provide a method to realize a selective film formation in the preparation of a light-emitting device using polymeric organic compound(s). SOLUTION: The organic compound layer consisting of plural materials is formed by coating application solution 108 in which the organic compound is dissolved in a solvent on a substrate 101 at which a mask 102 is installed. Further, this mask 102 is fully contacted with the circuit board 101, and a suction body 103 is installed so that a shift will not occur in the film-formation, thereby an organic compound layer is formed in a superior precision. |
