Problems solved by technology

In the actual production process, due to the limitations of the factory's process capability and the shrinkage rate of the color-resist material, the color blocking difference in the overlapping area is relatively large, and the so-called "bull horns"15 are formed in the overlapping area, which makes the In the subsequent process of printing the PI layer, the climbing ability of PI in this area is not good, and even the PI layer is not formed, resulting in a difference between the alignment of the liquid crystal molecules in the liquid crystal layer close to this area and the effective display area corresponding to the color resist layer 13. The initial arrangement of molecules is wrong, and because this area is not blocked by the black matrix, there will be light leakage

[0051] The sectional view of the color filter substrate of the first embodiment of the present invention is as follows figure 2 As shown, in this embodiment, the color filter substrate mainly includes: a substrate 21 , a black matrix layer 22 , a color resist layer 23 and a transparent conductive layer 24 . The substrate 21 is transparent, and may be a hard substrate made of glass, quartz, etc., or a flexible substrate made of plastic, polymer material, or the like. The color-resist layer 23 is directly formed on the substrate 21. Same as the prior art, the different areas of the color-resist layer 23 are respectively set as red (R), green (G), and blue (B) color-resist. The light is displayed as red, green and blue respectively, and the red (R), green (G), and blue (B) color resists are closely adjacent or there are gaps. The transparent conductive layer 24 is located on the color resist layer 23, and the material of the transparent conductive layer 24 is required to be a tra...

Abstract

The invention proposes a manufacture method for colored filter substrates, which adopts photochromic material to manufacture a black matrix layer and forms the black matrix layer by exposing the photochromic material which is coated in a whole layer, thus not needing to remove the areas among all the black matrixes in the black matrix layer by developing and avoiding the inserted overlap of a color resisting layer and the black matrix layer. The invention also proposes a colored filter substrate manufactured by the method and a liquid crystal display panel. As the overlap area of the color resisting layer and the black matrix layer does not have 'oxhorn', light leakage caused by poor grade ability of PI or no forming of a PI layer does not occur during the follow-up manufacture processes; as the developing process is not needed, the manufacture period and cost of the colored filter substrate are reduced; and when the pixel of the manufactured colored filter substrate generates lightspot, the methods of ultraviolet irradiation and the like can be used for repair.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a color filter substrate, a manufacturing method and a liquid crystal display panel. Background technique [0002] Liquid Crystal Display (LCD) not only has the characteristics of being light, thin, and small, but also has the advantages of low power consumption, no radiation, and relatively low manufacturing cost, so it currently occupies a dominant position in the field of flat panel display. Liquid crystal displays are ideally suited for use in desktop computers, palmtop computers, personal digital assistants (Personal Digital Assistant, PDA), cellular phones, televisions, and a variety of office automation and audio-visual equipment. [0003] The liquid crystal display panel is the main component of the liquid crystal display. The current mainstream liquid crystal display panel is composed of a thin film transistor (Thin Film Transistor, TFT) substrate and anot...
