1. A color filter substrate, comprising:
a base substrate;
a color filter layer disposed on the base substrate, wherein the color filter layer comprises a plurality of color resist units distributed on the base substrate, an intersection area is defined between two adjacent color resist units, and a manufacturing material of the color resist units comprises a photoresist material and a conductive material; and
a black matrix disposed on the base substrate;
wherein parts of two adjacent ones of the plurality of color resist units with different colors in the intersection area overlap each other, and a thickness of the parts of the plurality of color resist units located in the intersection area is less than a thickness of another parts of the plurality of color resist units; the black matrix is disposed in the intersection area between two adjacent ones of the plurality of color resist units with a same color, and the intersection area between two adjacent ones of the plurality of color resist units with different colors is not provided with a black matrix.
