PROBLEM TO BE SOLVED: To provide a method for manufacturing a flexographic printing plate that excels in tensile strength in a seamed portion, and particularly, has enough durability to a tensile stress repeatedly applied to the plate in a process of continuously printing a large liquid crystal alignment film or the like, and that prevents tearing or peeling at a seamed portion during printing a predetermined number of sheets, and a method for manufacturing a liquid crystal display element using a flexographic printing plate manufactured by the above method.SOLUTION: The method for manufacturing a flexographic printing plate includes steps of treating each side face 14 of a plurality of division pieces 4 with a treating agent comprising at least one compound selected from a group consisting of chlorine-containing compounds and cyanuric acid derivatives, then arranging the division pieces on the same plane as spaced at a predetermined interval in the plane direction, filling a gap 19 with a photosensitive resin composition 20, irradiating the resin composition with active rays to cure and joining the division pieces 4 by the cured product 5 to form an ink transfer layer 6. The method for manufacturing a liquid crystal display element includes a step of forming a liquid crystal alignment layer by flexographic printing using the above flexographic printing plate.SELECTED DRAWING: Figure 1 |
