Abstract

The invention discloses a manufacturing method of a liquid crystal alignment layer. The method comprises the following steps: (1) a deposition bin is arranged, and a glass substrate and a gas distributor are respectively arranged at both sides of the deposition bin; (2) the deposition bin is vacuumized; (3) the glass substrate is heated to the required temperature; (4) the deposition bin is filled with hydrocarbon gas and inert gas; (5) high frequency voltage is applied to the glass substrate and the gas distributor, the gas reacts under the action of the electric field and under the condition of gas pressure, and an alignment film is formed on the surface of the glass substrate; and (6) the bombarding is performed to the alignment film through an ion gun to form an alignment groove, so that a liquid crystal alignment layer is formed. The invention also discloses a manufacturing method of the other kind of liquid crystal alignment layer, and the alignment film is formed by a sputtering method and then is bombarded through the ion gun to form an alignment groove, so that a liquid crystal alignment layer is formed. The invention enables the alignment of the liquid crystal alignment layers to be more consistent to further improve the display quality of the liquid crystal display; and in addition, the manufacturing cost can be also reduced.

Description

technical field

[0001] The invention relates to liquid crystal display technology, in particular to a method for manufacturing a liquid crystal alignment layer. Background technique

[0002] 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, so that the liquid crystal molecules can be aligned or arranged in a specific direction on the surface.

[0003] At present, the general production process of the liquid crystal alignment laye...
