Patent number: 9387715Abstract: In order to prevent protruded parts formed on an oriented film print pattern of a printing plate for flexographic printing from being lost, a linear bank is formed on the periphery of one side of the oriented film print pattern where wiping work is started. The bank prevents the protruded part in the oriented film print pattern from being lost by the wiping work. The protruded parts are formed in a matrix in order to retain an oriented film liquid in the oriented film print pattern. Thickness irregularity of the oriented film due to presence of the bank is reduced by making the diameters of the protruded parts smaller in a peripheral region than in a central region of the oriented film print pattern and forming a space between the peripheral-side protruded parts and the bank.Type: GrantFiled: December 17, 2013Date of Patent: July 12, 2016Assignee: JAPAN DISPLAY INC.Inventors: Shunsuke Yuge, Hiroshi Miyairi
