Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0033] An embodiment of the present invention provides a method for manufacturing a color filter. By mixing a solvent compatible with the pixel resin material into the pixel resin material, micropores are formed on the pixel resin layer by utilizing the volatilization of the solvent during the pre-baking process. . The method can be realized only by prolonging the pre-baking time in the pre-baking stage of the existing color filter production process, which simplifies the process of opening holes in the pixel area, thereby reducing the production cost.
[0034] The structure of the color filter formed by the embodiment of the present invention is as follows figure 1 and figure 2 As shown, it includes: a substrate 1, a black matrix 2 formed on the...

Abstract
A method for manufacturing a color filter, the color filter, and a display device. The manufacturing method comprises: forming a black array (2) on a substrate (1); coating a pixel resin material (3) onto the substrate (1) having formed thereon the black array (2), where the pixel resin material (3) has added therein a first solvent miscible with the pixel resin material (3); performing a first thermal treatment on the substrate (1) having coated thereon the pixel resin material (3), thus allowing for evaporation of the first solvent in the pixel resin material (3) to form pores (9); by using a mask having engraved thereon a first pattern, exposing the thermally treated substrate (1), and, after development and a second thermal treatment, forming a pattern of the pixel resin layer. This method for manufacturing the filter allows for simplified process for pore-forming in a pixel area of the color filter, thus reducing manufacturing costs.
Description
technical field [0001] The invention relates to the field of liquid crystal display, in particular to a color filter and a manufacturing method thereof, a material for making the color filter, a liquid crystal display panel and a display device. Background technique [0002] In order to achieve higher transmittance and brightness of the color filter, in the prior art, holes are often used in the pixel area of the color filter to achieve this. In the prior art, the realization of the color opening technology is to use a mask plate with a pattern of micro-holes, and form micro-holes in the pixel resin layer (color resin layer) through exposure and development processes. This method of opening holes requires a complicated process, and requires the manufacture of a specific mask to realize the opening of the pixel area, and the cost is relatively high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a color filter...
