Abstract:
1. A process for producing an organic light-emitting display device having at least one organic compound layer on an electrode provided on a substrate, comprising the steps of: aligning the substrate with a mask by an alignment mechanism; pressing the aligned substrate against the mask from a central part toward a periphery of the substrate by a pressing member to temporarily fix the substrate to the mask; closely fixing the substrate and the mask which are temporarily fixed by the pressing member by a magnetization unit; and forming an organic compound layer on the substrate through the closely fixed mask by vapor deposition, wherein the substrate is temporarily fixed to the mask at a plurality of positions by a plurality of pressing members, respectively, and wherein when the substrate is temporarily fixed to the mask, pressing times or pressing strengths of the plurality of pressing members are different on a surface of the substrate.
