Abstract:
A method of manufacturing an organic thin-film electroluminescent device in which a plurality of thin-film luminescent portions, each of which is formed by organic electroluminescent material or electrode material, are arranged with fine pitches on a substrate, comprising the steps of;arranging a mask pattern on a pattern mask moving stage which finely moves in a predetermined direction;arranging the substrate on a substrate moving stage;opposing the substrate against the pattern mask with a predetermined pitch;performing an initial positioning alignment between the substrate and the pattern mask by adjusting the substrate moving stage;vaporizing the luminescent material onto a surface of the substrate through the pattern mask;vaporizing the luminescent material on the surface of the substrate after moving the pattern mask onto a non-vaporizing portion of the surface of the substrate by moving the pattern mask moving stage in parallel to the substrate; andwhereby, forming arrangement of the luminescent portions on the surface of the substrate.
