1. A color film substrate, comprising a base substrate, a black matrix layer, a color-resist layer, a protective layer, and a supporting post layer that are stacked and provided in sequence; wherein, the black matrix layer is provided with light-transmitting windows distributed in an array, the color-resist layer covers each light-transmitting window, and the supporting post layer is provided with a supporting post;
the color film substrate comprises a plurality of different subregions;
in at least part of the subregions, the color-resist layer is provided with a partition slot located between rows of the light-transmitting windows and exposing the black matrix layer, and an orthographic projection of the supporting post on the base substrate at least partially overlaps with an orthographic projection of the partition slot on the base substrate;
wherein, in at least two of the subregions, the partition slot is provided with different widths, and a width of the partition slot is a size of the partition slot in a column direction.
