Claim 0:
1. A color filter substrate, wherein the color filter substrate comprises a first substrate, a color filter functional layer, and a first polarizing component that are stacked with one another, and the first polarizing component comprises:
at least one first dielectric layer;
a first dielectric grating layer, wherein the first dielectric grating layer is stacked with the first dielectric layer, and ridges and grooves are arranged at intervals periodically on one side of the first dielectric grating layer away from the first dielectric layer;
a first polarizing layer, wherein the first polarizing layer is located in the grooves of the first dielectric grating layer; and
a second polarizing layer, wherein the second polarizing layer is located on the ridges of the first dielectric grating layer;
wherein a spacing between a top of the first polarizing layer located in each of the grooves and a top of the second polarizing layer located on the ridges adjacent to the each of the grooves in an arrangement direction of the grooves is 0.
