Abstract

The invention discloses a printing relief plate, which comprises a bearing bottom plate and a plate body for printing, wherein the plate body for printing is provided with a bottom surface, and the bottom surface is contacted with the bearing bottom plate; and the plate body for printing comprises a central area and a marginal area, a first convex part is formed in the central area, a second convex part is formed in the marginal area, the first convex part is provided with a first top surface opposite to the bottom surface, the second convex part is provided with a second top surface opposite to the bottom surface, and the distance between the second top surface and the bottom surface is smaller than the distance between the first top surface and the bottom surface. According to the printing relief plate, an orientation material can be uniformly printed on a glass substrate so as to prevent a cured orientation film from generating marginal effect and forming a lug in the marginal area, enlarge the effective display area of a liquid crystal display screen and improve the display effect.

Description

technical field [0001] The invention relates to a printing letterpress, in particular to a printing letterpress for printing an alignment film of a liquid crystal display. Background technique [0002] Printing letterpress can be used for various printing. In recent years, printing letterpress has been widely used in the production process of liquid crystal display. Its main function is to use letterpress printing method to print the alignment material On the glass substrate, an alignment film is formed on the glass substrate, so that the liquid crystal molecules can be arranged on the glass substrate according to certain rules. refer to figure 1 , the process of printing the alignment material on the glass substrate is as follows: the anilox roll 11 (anilox roll) rotates counterclockwise, the printing roll 12 (printing roll) rotates clockwise, and at the same time drives the printing relief 13 on it to rotate clockwise, and the glass substrate 14 (glass) moves to the left...
