With the development of electro-optical and semiconductor technology, Liquid Crystal Displays (LCDs) have been developed vigorously. Among many liquid Crystal displays, a Thin Film transistor liquid Crystal Display (TFT-LCD) has superior characteristics of high space utilization efficiency, low power consumption, no radiation, low electromagnetic interference, and the like. In the information society of today, TFT-LCDs have been widely used in various aspects of life, from small-sized mobile phones, video cameras, digital cameras, medium-sized notebook computers, desktop computers, large-sized home televisions, to large-sized projection devices, and the like. The TFT-LCD is the key point in the market of displays on the basis of the advantages of lightness and thinness, and the characteristics of perfect picture and quick response.

Generally, a liquid crystal display includes a housing, a liquid crystal display panel disposed in the housing, and a Backlight module (Backlight module) disposed in the housing. The Liquid Crystal display panel is mainly composed of a Thin film transistor Array Substrate (TFT Array Substrate), a Color Filter Substrate (CF), and a Liquid Crystal Layer (Liquid Crystal Layer) disposed between the two substrates, and the Liquid Crystal display panel has an operation principle that a driving voltage is applied to the two glass substrates to control the rotation of Liquid Crystal molecules of the Liquid Crystal Layer, so as to refract light of the backlight module to generate a picture.

The Cell gap is the thickness of the liquid crystal layer disposed between the array substrate and the color filter substrate, and the Cell thickness is an important parameter affecting the performance of the liquid crystal display panel. The uneven cell thickness is represented by a larger cell thickness or a smaller cell thickness, and according to transmittance formulas of three display modes of TN, IPS and VA, the luminance is higher when the cell thickness is larger, and the luminance is lower when the cell thickness is smaller. Specifically, if the normal region is yellowish, the observed Mura whitening can be basically determined as a small box thickness, and the observed Mura purple can be basically determined as a large box thickness. If the normal area is blue, the observed Mura is dark blue and can be basically judged as small box thickness, the observed Mura whitening can be basically judged as large box thickness, and other display defects are generated.

In view of the above, it is a problem to be solved to provide a liquid crystal display panel with improved cell thickness uniformity.
