A liquid crystal display panel and its manufacturing method

Abstract

The invention discloses a multi-domain vertically-orientated LCD (Liquid Crystal Display) panel and a manufacturing method thereof, which is used for simplifying the manufacture procedure of the multi-domain vertically-orientated LCD panel, belonging to the field of LCD. The LCD panel comprises a slit structure which is arranged on an insulating layer above a pixel electrode, the different thicknesses of two adjacent sub-pixel upper insulating layers are prepared by a half grey-scale photomask technology, so as to obtain different insulating layer capacitors; according to a capacitance partial-pressure principle, the voltage differences at the two ends of first and second sub-pixel liquid crystal capacitors are different, so as to influence the degree of dumping of liquid crystal modules, and realize the multi-domain display of the LCD. In addition, a structure which orientates the dumping of liquid crystal molecules through a shading matrix is correspondingly arranged at a colorful membrane side, and the liquid crystal molecules are dumped in a same direction, so as to accelerate the reaction time of liquid crystal, eliminate black streak phenomenon and improve penetration rate. By adopting the multi-domain vertical orientated LCD panel, either a bulge technology or a slit technology is not needed t at the colorful membrane side, the multi-domain is realized without a photo-alignment technology, the processing steps of manufacturing can be simplified, the product yield can be improved, and the cost can be reduced.

Description

technical field [0001] The present application relates to the field of liquid crystal display technology, in particular to a multi-domain vertical alignment type 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 (mult...

Problems solved by technology

[0006] However, the problem is that if the protrusions are placed on the color filter substrate, it will cause light leakage, which will reduce the contrast of the liquid crystal display panel. Moreover, it needs to add an exposure and development process on the color filter substrate, which makes the manufacturing process complicated and relatively expensive. high

In addition, although the emerging ultraviolet light alignment technology eliminates the need for protrusions or slit structures on the side of the color filter, it needs to increase the optical alignment process, which also increases the process flow, and the optical alignment yield and product reliability need to be improved.
