Abstract

The invention discloses a transfer printing plate. The problem that a printed orientation film is uneven in thickness through an existing transfer printing plate structure, so that following friction orientation is not even, and accordingly liquid crystal molecular orientation is abnormal is solved. The transfer printing plate comprises a base film and net point arrays formed by a plurality of net points placed on the base film. The base film is divided into an active zone and a non-active zone surrounding the active zone. The active zone corresponds to a liquid crystal display zone. The net point array in the active zone has a first net point angle. The net point array in the non-active zone has a second net point angle. The second net point angle is smaller than the first net point angle.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a transfer printing plate. Background technique [0002] In the manufacturing process of Thin Film Transistor Liquid Crystal Display (TFT-LCD), it is necessary to coat a layer of alignment agent on the glass substrate of the liquid crystal cell to form a uniform alignment film. The liquid crystal molecules covered on it are arranged along a certain direction, and the liquid crystal molecules are deflected according to the specified direction according to the control of the electric field, so that the final liquid crystal display panel including the liquid crystal cell can display normally. [0003] Among them, the process of forming an alignment film on a glass substrate is as follows: figure 1 As shown, first, the alignment agent 101 is dripped to the contact position between the cot roller 103 and the scraper 104 through the dispenser 102, and then the alignment agent 101 on ...
