Problems solved by technology

[0007] However, the problem is that in the above-mentioned liquid crystal display panel, in order to realize the pre-tilt of the liquid crystal molecules after the voltage is applied, it is necessary to increase the process steps of manufacturing cracks or protrusions. The photolithography process is realized; in this way, at least one mask etching process is added in the manufacturing process of the liquid crystal display panel, and the manufacturing process steps are increased, which will affect the product yield and increase the manufacturing cost.

Abstract

The invention provides a liquid crystal display panel and a manufacturing method thereof. The liquid crystal display panel comprises a first substrate, a second substrate which is opposite to the first substrate and a liquid crystal layer which is arranged between the first and the second substrates, wherein under the situation of non-electrification, liquid crystal molecules in the liquid crystal layer are arranged to be vertical to the first substrate, and the liquid crystal layer comprises an anchoring substance; the liquid crystal molecule which is close to the surface of the first substrate or the second substrate is pre-inclined under the situation of non-electrification through the anchoring substance. The liquid crystal display panel and the manufacturing method thereof are free from forming projection or crack and from changing other structures of a pixel unit, can realize the pre-inclination of the liquid crystal molecules, can simplify the manufacturing process procedure, can improve the yield of the product, and can reduce the cost.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display panel and a manufacturing method thereof. Background technique [0002] In recent years, large-sized, thin and light flat-panel displays have gradually taken center stage in the display market. According to the display principle, the flat panel display may include: a liquid crystal display (Liquid Crystal Display, LCD), a plasma display, an organic electroluminescent display, and the like. [0003] Among various display modes of liquid crystal displays, a vertical alignment (Vertical Alignment, VA) display mode is popular in the market due to its good viewing angle characteristics. In the LCD of the VA display mode, the long axis of the liquid crystal molecules in the pixel unit is perpendicular to the filter in the state of no power, and each pixel unit is divided into multiple domains (multi-domains). , the liquid crystal molecules in e...
