印刷用凸版及びそれを用いた凸版印刷装置、並びに有機エレクトロルミネッセンス素子の製造方法
Document Type and Number:
Japanese Patent JP5699511
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a relief printing plate which can allow a uniform film to be formed when used for forming the film having an organic layer by a relief printing method and to provide a method for producing an organic EL element, which has no luminance nonuniformity when light is emitted therefrom, by using the relief printing plate and to provide a method for producing an electronic device.SOLUTION: The relief printing plate comprises a projection pattern obtained by forming one or more striped projections, each of which is longer in the direction parallel to the printing direction, on a base material. The striped projection has a projection pattern outer circumferential part to be contacted with, at the least, an outer circumferential part of a substrate to be printed and a projection pattern central part to be contacted with a central part of the substrate to be printed. The relief printing plate is used in the relief printing method in which the ink supplied onto the striped projections by an ink supply means is transferred to the substrate to be printed. The width of the striped projection is made uniformly narrower as it goes to the projection pattern outer circumferential part from the projection pattern central part.
