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 with figure 2 As shown, it includes: a substrate 1, a black matrix 2 formed on th...

Abstract

The invention provides a color filter, a manufacturing method thereof, materials for manufacturing the color filter, a liquid crystal display panel and a display device, and belongs to the field of liquid crystal display. The manufacturing method includes forming a black matrix on a substrate; coating a pixel resin material on the substrate added with a first solvent capable of being dissolved in the pixel resin material; performing first heat treatment for the substrate coated with the pixel resin material so that the first solvent in the pixel resin material is volatilized to form micropores; and exposing the substrate by a mask plate engraved with a graph after the substrate is subjected to the first heat treatment, and forming a graph of a pixel resin layer after development and second heat treatment. The process of perforating a pixel zone of the color filter can be simplified, so that production cost is lowered.

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...
