Color filter substrate, manufacturing method thereof, and display device

Abstract

The invention provides a manufacture method of a color film substrate. The manufacture method comprises the steps that a masking pattern is formed on a first surface of a substrate, and comprises a hollowed-out part and a lightproof part, the lightproof part comprises a first lightproof subpart, the thickness of the first lightproof subpart is less than that of other parts of the lightproof part; a black matrix material layer is formed on a second surface of the substrate; the black matrix material layer is exposed and developed from one side where the masking pattern is formed, so that a black matrix is formed; ashing is performed for the first time to remove the first lightproof subpart, and one part of the other parts of the lightproof part is kept; a color resistance material layer of a first color is formed on the second surface of the substrate; the color resistance material layer of the first color is exposed and developed from one side where the masking pattern is formed, so that a color resistance block of the first color is formed. Correspondingly, the invention also provides a color film substrate and a display device. Through the invention, the usage quantity of mask plates can be reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a color filter substrate, a manufacturing method thereof, and a display device. Background technique [0002] The liquid crystal display panel includes an array substrate and a color filter substrate boxed together, and a liquid crystal layer located between the array substrate and the color filter substrate. Such as figure 1 As shown, the color filter substrate includes a base substrate 1 , a black matrix 2 and color-resist blocks 3 of various colors, and each sub-pixel area of ​​the color filter substrate is provided with a color-resist block 3 of a corresponding color. Currently, in the production process of color filter substrates, different masks are usually used to manufacture the black matrix 2 and color-resist blocks 3 of different colors. For example, when the color filter substrate includes sub-pixels of red, green and blue When making the black matrix, red color-res...

Problems solved by technology

Currently, in the production process of color filter substrates, different masks are usually used to manufacture the black matrix 2 and color-resist blocks 3 of different colors. For example, when the color filter substrate includes sub-pixels of red, green and blue When making the black matrix, red color-resist block, green color-resist block, and blue color-resist block, each use a mask for exposure, the number of masks used is large, resulting in high production costs
