Photomask assembly, liquid crystal display panel, color filtering substrate and preparation method of color filtering substrate

Abstract

The invention discloses a photomask assembly, a liquid crystal display panel, a color filtering substrate and a preparation method of the color filtering substrate. The color filtering substrate comprises an underlayer, a first filtering film, a second filtering film and a third filtering film, and the first filtering film, the second filtering film and the third filtering film are formed on the underlayer. The first filtering film comprises a first color resistor and a first surrounding color resistor, the second filtering film comprises a second color resistor and a second surrounding color resistor, and the third filtering film comprises a third color resistor and a third surrounding color resistor. The color resistors are arranged at different positions of the underlayer, and each surrounding color resistor and another surrounding color resistor are at least arranged on the edges of the four sides of the color resistor in an overlapped mode to form a black matrix; a spacer is formed above the black matrix through the surrounding color resistor located on the uppermost layer. According to a color film substrate, the peripheries of the color resistors are overlapped to form the black matrixes through the surrounding color resistors, no additional preparation material is needed, only three manufacturing procedures are needed, the preparation cost is reduced, and meanwhile the preparation time is shortened.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a photomask assembly, a liquid crystal display panel, a color filter substrate and a preparation method thereof. Background technique [0002] Liquid Crystal Display (LCD) is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, and is placed in front of a light source or a reflective surface. Liquid crystal displays have low power consumption, high image quality, small size, and light weight, so they are favored by everyone and become the mainstream of displays. At present, the liquid crystal display is mainly a thin film transistor (Thin Film Transistor, TFT) liquid crystal display, and the liquid crystal panel is a main component of the liquid crystal display. A liquid crystal panel generally includes a color filter substrate and a TFT array substrate disposed opposite to each other, and a liquid crystal layer sandwiched...

AI Technical Summary

Problems solved by technology

Among them, the preparation of the color filter substrate is mainly through 6 processes to prepare the black matrix, red color resistance, green color resistance, blue color resistance, isolation layer and transparent electrode layer; and in the 6 processes, except for the transparent electrode layer, no mask is required. In addition, the rest of the parts need masks, that is, 5 masks are required to prepare, resulting in a long preparation process and high cost
