Abstract:
1. An organic EL device manufacturing method including forming an organic layer on an electrode-layer side of a strip-shaped substrate, while moving the substrate, the electrode-layer side being provided with an electrode layer, comprising: a vapor deposition step of supplying the strip-shaped substrate, and while moving the substrate with a non-electrode-layer side thereof 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 arranged so as to face the can roller to form an organic layer on the electrode-layer side of the substrate, the non-electrode layer side being provided with no electrode layer, wherein the vapor deposition step further comprises: and wherein the projections each have a taper shape tapering from a can roller side thereof toward a distal end thereof, and a diameter of the through holes of the shadow mask is smaller than a diameter of the through holes of the substrate such that when through holes of the shadow mask and the substrate are fully engaged with the projections, a gap is formed between the shadow mask and the substrate.
