Problems solved by technology

The above horn phenomenon will cause poor surface flatness of the color-resist layer of the color filter, which will further cause the ITO (Indium Tin Oxide, indium tin oxide) conductive film formed behind the color-resist layer to easily crack

Embodiment Construction

[0030] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

[0031] At present, the manufacturing process of color filters mainly includes the following steps: first, a black matrix layer is formed on the substrate; then, color-resist materials (which belong to photoresist materials) are sequentially coated on the black matrix layer and correspondingly carried out respectively. Exposure, development, and curing are performed to form a corresponding color-resist layer; ...

Abstract

The invention discloses a color filter, a liquid crystal display panel and a method for producing the color filter. The method for producing the color filter comprises steps of: coating a substrate with a first photoresist material and processing to form a black matrix layer with a plurality of spacer regions; coating the black matrix layer with a photoresist material different from the first photoresist material, processing by laser beam at a preset position, and then exposing developing and solidifying to form a color resistance layer in each spacer region; coating the color resistance layer with a conductive material to form a conductive film and consequently obtain the color filter. According to the color filter, the liquid crystal display panel and the method for producing the color filter, the ox horn phenomenon of the color resistance layer in the color filter can be eliminated or reduced, the surface plainness of the color resistance layer is improved, the situation that ITO conductive film is easy to fracture at the position where the cattle horn phenomenon occurs on the color resistance layer is improved, and thereby the performance of the color filter is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a method for manufacturing a color filter, a color filter and a liquid crystal panel. Background technique [0002] In the existing liquid crystal panel production process, the production of color filters mainly includes several steps of photoresist coating, exposure, development and curing. In the manufacturing process of color filters, since multiple photoresist materials are sequentially coated on the substrate layer by layer to form a color resist layer, this may lead to uneven defects similar to horns in the overlapping parts of different photoresist materials , that is, the horn phenomenon, such as figure 1 and figure 2 indicated by the arrow in the. The horn phenomenon mentioned above will cause poor surface flatness of the color-resist layer of the color filter, which will further cause the ITO (Indium Tin Oxide, indium tin oxide) conductive film formed...
