The invention discloses a color filter substrate, a manufacturing method of the color filter substrate and a display panel, relates to the field of display technology, and mainly aims to solve the problem of relatively large errors in the testing process of spacers in the prior art. The main technical solutions of the present invention include: a base substrate and a black matrix layer arranged on the base substrate; a color filter layer, the color filter layer is arranged on the base substrate; a plurality of auxiliary structures are arranged on The surface of the black matrix layer away from the base substrate; the surface of the auxiliary structure away from the base substrate is a horizontal plane, and the surface of the auxiliary structure is used for setting spacers; a plurality of the auxiliary structures The step difference between the surfaces is smaller than the first threshold; wherein, the orthographic projection of the auxiliary structure on the base substrate is located within the orthographic projection of the black matrix on the base substrate, and is in line with the color The orthographic projections of the film layers on the base substrate do not overlap.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a color filter substrate, a manufacturing method of the color filter substrate, and a display panel. Background technique [0002] In the field of display technology, liquid crystal panels occupy the display panel market due to their advantages of low power consumption, thinness, and portability. The liquid crystal panel includes a color filter substrate, an array substrate, and a liquid crystal layer located between the color filter substrate and the array substrate. Realize by making spacers on top. [0003] The spacer is divided into main spacer and auxiliary spacer. The main spacer has a certain amount of compression, the support box is thick, and is in a compressed state, while the auxiliary spacer has no compression. When the liquid crystal panel is subjected to excessive external force, the auxiliary spacer is compressed to play an auxiliary supporting role. At...
