Abstract:
1. An organic EL element manufacturing method comprising: forming a pixel electrode on a substrate; forming a partition wail which surrounds a periphery of the pixel electrode; coating ink which contains a functional layer forming material in a coating region which is surrounded by the partition wail; and forming a functional layer in the coating region by drying the ink which is coated, wherein in the forming of the partition wall, the partition wall is formed such that a side surface of the partition wall which intersects with respect to a surface of the pixel electrode forms an angle of 40 degrees to 60 degrees with respect to the surface of the pixel electrode, and in the coating of the ink, the ink is coated so as to satisfy the following expressions (1) to (3), in a case where a contact angle of the ink with respect to the side surface of the partition wall is set to θbc and the contact angle with respect to a surface of the coating region where the ink is coated is set to θlc
