Problems solved by technology

Generally, the conductive layer 140 of a transmissive liquid crystal display is made of indium tin oxide (ITO). However, due to excessive pressure on the surface of the panel, the ITO under the spacers will be broken, which will cause local The cell gap between the regions is abnormal, resulting in uneven brightness between the region and other regions, which affects the characteristics of the display
[0009] In addition, the general thin film transistor liquid crystal display uses the electric field between the conductive layer (or patterned conductive layer) on the thin film transistor matrix substrate and the color filter substrate to control the liquid crystal layer arranged between the two substrates, so if the two substrates There is a conductive foreign object in between, which will also affect the electric field configuration and cause the pixel at the location of the foreign object to fail, thereby forming a constant bright or dark point, which affects the viewing quality of the display

Description

technical field [0001] The invention relates to a display device, and in particular to a color filter substrate and a manufacturing method thereof, a liquid crystal display panel and a liquid crystal display device. Background technique [0002] Due to the increasing demand for displays, the industry is fully committed to the development of related displays. Among them, the cathode ray tube (CRT) has monopolized the display market for many years because of its excellent display quality and technological maturity. However, due to the rise of the concept of green environmental protection, the characteristics of large energy consumption and large radiation, and the limited space for flat products, it cannot meet the market's requirements for lightness, thinness, shortness, smallness, beauty and low consumption. Power Market Trends. Therefore, thin film transistor liquid crystal displays (Thin Film Transistor Liquid Crystal Display, TFTLCD) with superior characteristics such a...
