Color filter and production method thereof as well as liquid crystal panel

Abstract

A colour filter, a manufacturing method therefor, and a liquid crystal display panel. The colour filter (1) comprises a substrate (10), and black matrixes (11), spacers (12) and a colour filter layer (13) which are formed on the substrate (10). The black matrixes (11) and the spacers (12) are of an integral structure, and the thickness of the black matrixes (11) is greater than that of the colour filter layer (13). The colour filter layer (13) is formed by adding colour ink between black matrixes (11) on the substrate (10) through an inkjet printing method and curing same. Because the black matrixes (11) and the spacers (12) are formed in one piece by exposing and developing a black film on the substrate (10), the fabrication process for a colour filter is simplified. Because the colour filter layer (13) is formed by an inkjet printing method, the height of the black matrixes (11) is not limited in the process of forming the colour filter layer (13). Therefore, the black matrixes (11) and the spacers (12) can be made of the existing material, thereby improving the manufacturing yield of colour filters.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter, a manufacturing method of the color filter and a liquid crystal panel. Background technique [0002] Liquid Crystal Display (LCD) is a flat panel display device (Flat Panel Display, FPD) that uses the characteristics of liquid crystal materials to display images. Compared with other display devices, it has thinner, lower driving voltage and lower power consumption. Consumption and other advantages, has become the mainstream product in the entire consumer market. The liquid crystal display panel is composed of a color filter and a TFT array substrate, and gap particles are arranged between the two to form a gap for liquid crystal injection. The interstitial particles are generally disposed on a color filter. [0003] Such as figure 1 As shown, the existing color filter includes a substrate 101, a black matrix 102 disposed on the substrate 101, a c...

Problems solved by technology

Therefore, in order to meet the requirement of the gap between the two substrates, unless the black matrix 102 and the interstitial particles 105 are made of a new material with a very high light sensitivity, the new material with a very high light sensitivity will also vary depending on the machine in the actual process. Unstable black film thickness due to energy difference, which will increase the defective rate of subsequent processes
