Abstract
A manufacturing method of a color filter substrate is provided. The manufacturing method includes steps of providing a substrate comprising a color filter region and a black matrix region; depositing a black matrix layer on a surface of the substrate in the black matrix region; applying an RGB color resist to the color filter region of the substrate; correspondingly forming a plurality of photo spacers on a surface of the black matrix, the photo spacers being made from light-shielding material; forming a protective layer above the substrate. The photo spacers made from light-shielding material is arranged on the surface of the black matrix to prevent the transmission of light rays through the RGB color resist that results in mixture of colors.

A manufacturing method of a color filter substrate, comprising steps of:
- step S10, providing a substrate comprising a color filter region and a black matrix region;
- step S20, depositing a black matrix layer on a surface of the substrate, and patterning the black matrix layer to form a black matrix so as to completely remove portions of the black matrix layer within the color filter region;
- step S30, applying an RGB color resist to the color filter region of the substrate;
- step S40, correspondingly forming a plurality of photo spacers on a surface of the black matrix, the photo spacers being made from a light-shielding material, the length of the photo spacers being equal to that of a long side of the RGB color resist;
- and
- step S50, forming a protective layer above the substrate, the protective layer entirely covering the black matrix, the photo spacers and the RGB color resist,
- wherein the photo spacers made from the light-shielding material are arranged on the surface of the black matrix to prevent the transmission of light rays through the RGB color resist that results in mixture of colors.
