1. A color film substrate comprising:
a substrate;
a first black matrix located on the substrate; and
a second black matrix partially overlapping with the first black matrix, wherein at an overlapping position of the first black matrix and the second black matrix, the second black matrix overlays the first black matrix in a direction perpendicular to the substrate, wherein a size of an opening defined by either of the first black matrix and the second black matrix is greater than a size of an opening defined by the first black matrix and the second black matrix together, and wherein an orthographic projection of the first black matrix on the substrate and an orthographic projection of the second black matrix on the substrate together form a grid pattern
wherein the first black matrix comprises at least a plurality of first black matrix strips extending in a first direction, and the second black matrix comprises at least a plurality of second black matrix strips extending in a second direction different from the first direction and intersecting with the plurality of first black matrix strips, and wherein the overlapping position of the first black matrix and the second black matrix comprises an intersection position of the plurality of first black matrix strips and the plurality of second black matrix strips, and
wherein the first black matrix further comprises a plurality of fourth black matrix strips extending in the second direction and intersecting with the plurality of first black matrix strips, wherein the plurality of fourth black matrix strips are arranged dispersedly among the plurality of second black matrix strips such that there is at least one second black matrix strip between two adjacent fourth black matrix strips, and wherein each of the plurality of fourth black matrix strips and each of the plurality of second black matrix strips have a substantially same width and a width of each of the plurality of fourth black matrix strips is greater than a width of each of the plurality of first black matrix strips.
