Method for manufacturing color filter substrate

A method for manufacturing a color filter substrate comprising:

• providing a substrate;
• forming a first conductive black matrix extending along a first direction on the substrate;
• forming a color film layer on the substrate, wherein the normal projections of the color film layer and of the first conductive black matrix on the substrate are not overlapping;
• forming a plurality of first spacers on the first conductive black matrix, wherein the height of the plurality of first spacers and the thickness of the first conductive black matrix in total are equal to the thickness of the color film layer, and the materials of the plurality of first spacers and of the color film layer are the same;
• forming a second conductive black matrix on the substrate, wherein the second conductive black matrix extends along a second direction and covers the plurality of first spacers, and the second direction intersects with the first direction;
• forming a passivation layer to cover the first conductive black matrix, the color film layer, the plurality of first spacers, and the second conductive black matrix;
• forming a transparent conductive layer on the passivation layer;
• and
• forming a plurality of second spacers on the transparent conductive layer, wherein the normal projections of the plurality of second spacers and of the plurality of first spacers on the substrate are overlapping.
