Abstract

The invention discloses a manufacture method of a liquid crystal orientation layer, comprising the following steps: (1) arranging a deposition cabin, arranging targets on the cathode side of the deposition cabin, and arranging a glass substrate on the anode side of the deposition cabin; (2) vacuumizing the deposition cabin; (3) filling inert gas into the deposition cabin; (4) applying direct-current high voltage on the glass substrate and the target, ensuring that the target sputters target atoms under the action of electric field and under certain gas pressure, and depositing on the glass substrate to form an orientation film, wherein the pressure of inert gas is 50-6000Pa; and (5) adopting an ion gun with a certain relative angle and an inclined angle with the glass substrate, carrying out ion bombardment on the orientation film arranged on the surface of the glass substrate, and forming an orientation slot on the orientation film so as to form the liquid crystal orientation layer. The invention can bring more consistent orientation of the liquid crystal orientation layer so as to improve the display quality of the liquid crystal display; in addition, the invention can lower the manufacture cost.

Description

[0001] This application is a divisional application of (application number: 200810102480.7, filing date: 2008-03-21, invention title: method for manufacturing liquid crystal alignment layer). technical field

[0002] The invention relates to liquid crystal display technology, in particular to a method for manufacturing a liquid crystal alignment layer. Background technique

[0003] In addition to other components such as polarizers and glass substrates, a liquid crystal display also includes a liquid crystal layer. The orientation behavior of the liquid crystal layer determines most of the optical properties of the liquid crystal display, and this orientation is determined by the orientation of the liquid crystal layer in contact with the liquid crystal layer. layer, the alignment layer is also called a liquid crystal alignment layer. The liquid crystal alignment layer provides a pretilt angle for the liquid crystal molecules close to the surface of the liquid crystal layer,...
