Abstract: An organic EL device manufacturing method includes a vapor deposition step of supplying a substrate, and while moving the substrate with a side thereof, on which an electrode layer is not provided, in contact with a surface of a can roller that rotates, discharging an evaporated organic layer forming material from a nozzle of a vapor deposition source to form an organic layer over a side of the substrate on which the electrode layer is provided, wherein the vapor deposition step is performed while, using a distance measuring section capable of measuring a first distance to the substrate supported by the can roller, and a position adjusting section capable of adjusting a second distance between the nozzle of the vapor deposition source and a surface of the substrate, control is performed by the position adjusting section so that the second distance is constant.

Abstract: A method for manufacturing an organic EL device, including: while supplying a strip-shaped substrate, forming an organic EL film on the substrate by successively vapor depositing at least an organic layer including a light-emitting layer and an electrode layer on one side of the substrate; and successively winding up the substrate on which the organic EL film is formed by the vapor deposition, wherein the substrate is wound up along with a strip-shaped protective film that is softer than the substrate while supplying the protective film and adhering the protective film to a non-vapor deposition side of the substrate.
