Problems solved by technology

However, the liquid crystal display device still needs to be equipped with alignment layers such as polyimide. In addition to the complexity of the manufacturing process, the high price of polyimide makes it impossible to effectively reduce the cost of manufacturing this type of liquid crystal display device.

Abstract

The invention provides a liquid crystal alignment composition and a method for manufacturing a liquid crystal display device through the liquid crystal alignment composition. The liquid crystal alignment composition mainly comprises a heterocycle monomer and an acrylic monomer, wherein the heterocycle monomer and the acrylic monomer mutually react and polymerize to form a liquid crystal alignment layer on the two corresponding surfaces of a base plate, and the two corresponding surfaces of the base plate are positioned in a liquid crystal accommodating space. Accordingly, when the liquid crystal display device is manufactured, the alignment layer does not need to be firstly arranged on the base plate, so that the manufacturing procedure and the cost can be effectively reduced.

Description

technical field [0001] The present invention relates to a liquid crystal alignment composition, in particular to a liquid crystal alignment composition with a heterocyclic monomer. The present invention also relates to a method of manufacturing a liquid crystal display device. Background technique [0002] Liquid crystal alignment technology is a key technology that determines the picture quality displayed by a liquid crystal display device. Only when the liquid crystal material in the liquid crystal display panel has a stable and uniform initial arrangement can a high-quality picture be presented. Generally, liquid crystal display devices have thin layers for inducing the alignment of liquid crystal molecules, which are called liquid crystal alignment layers. [0003] In the industrial process, the rubbing method is often used to arrange the liquid crystal molecules evenly. First, the liquid crystal alignment layer is mechanically rubbed, such as a uniformly moving plush ...
