1. A color filter substrate, comprising:
a base substrate, and
a light-shielding pattern on the base substrate and having a plurality of openings to define a plurality of pixel regions,
wherein each of the plurality of pixel regions at least comprises a color filtering region, and a color filtering layer is filled in each color filtering region, and
at least one of the plurality of pixel regions further comprises at least one transparent region, each of which is filled with a transparent non-filtering layer;
wherein in each pixel region with the transparent region, a ratio of an area of the transparent region to an area of the pixel region is in a range of (0, 0.36];
wherein each of the plurality of pixel regions comprises the transparent region, and each transparent region is filled with the transparent non-filtering layer, and
the transparent regions of the plurality of pixel regions have a same size and a same shape; and
wherein the plurality of pixel regions are arranged in an array along a first preset direction and a second preset direction; and each of the plurality of pixel regions is provided with two transparent non-filtering layers, which are arranged on two opposite sides of the color filtering layer along a first preset direction and the color filter layer is entirely arranged between the two transparent non-filtering layers.
