1. A color filter substrate, comprising:
a base substrate;
a color conversion layer on the base substrate;
a covering layer on a side of the color conversion layer away from the base substrate; and
a polarizing layer on a side of the covering layer away from the base substrate,
wherein the polarizing layer comprises a wire grid polarizer;
wherein the covering layer comprises a first covering sub-layer and a second covering sub-layer, the first covering sub-layer is located on the side of the color conversion layer away from the base substrate, the second covering sub-layer is located on a side of the first covering sub-layer away from the base substrate, and a material of the first covering sub-layer is different from a material of the second covering sub-layer; and
wherein the second covering sub-layer at least comprises a photoinitiator, and a difference in height of the second covering sub-layer is less than or equal to 100 nanometers.
