FLEXOGRAPHIC PRINTING PLATE AND METHOD FOR MANUFACTURING THE SAME, AND METHOD FOR MANUFACTURING SUBSTRATE FOR LIQUID CRYSTAL PANEL

摘要

PROBLEM TO BE SOLVED: To provide a flexographic printing plate and a method for manufacturing the flexographic printing plate that can be used for a long period of time, since the plate can disperse the contact pressure between an anilox roll, compared to a currently used system and can reduce wear, and to provide a method for manufacturing a substrate for a liquid crystal panel by using the above flexographic printing plate.SOLUTION: A flexographic printing plate 1 is roughened on a printing surface 2 in such a manner that an average length RSm of a roughness curve element is 0.1 times or more and 0.5 times or less of a pitch Pin a plane direction of a roughness pattern of an anilox roll 4 to be matched with the printing plate. The method for manufacturing the printing plate comprises: forming a layer of a photosensitive resin composition, which is a base material of the printing plate, on a shape-imparting surface; and irradiating the photosensitive resin composition with actinic rays to cure the photosensitive resin composition layer. The method for manufacturing a substrate for a liquid crystal panel comprises forming a liquid crystal alignment layer by flexographic printing by using the above flexographic printing plate.
