1. A color filter substrate, comprising:
a base substrate;
a color filter layer, disposed on a side of the base substrate and comprising a plurality of color photoresist units arranged in an array, the plurality of color photoresist units being formed with a plurality of color photoresist rows, a plurality of first color photoresist columns, a plurality of second color photoresist columns and a plurality of third color photoresist columns, wherein any one of the color photoresist rows comprises a first color photoresist unit, a second color photoresist unit, and a third color photoresist unit in periodic arrangement, any one of the first color photoresist columns comprises a plurality of first color photoresist units, any one of the second color photoresist columns comprises a plurality of second color photoresist units, and any one of the third color photoresist columns comprises a plurality of third color photoresist units, and wherein the color filter layer further comprises at least one filling part located between the color photoresist rows; and
a black matrix layer, disposed between the color filter layer and the base substrate, and comprising a plurality of light transmitting windows covered by respective color photoresist units in a one-to-one correspondence,
wherein
the at least one filling part comprises a first filling part located between two adjacent second color photoresist units within a same one of the second color photoresist columns and a second filling part located between two adjacent first color photoresist units within a same one of the first color photoresist columns, the first filling part has a different material from the second color photoresist unit, the second filling part has a different material from the first color photoresist unit,
the first filling part is contiguously disposed between the two adjacent second color photoresist units within the same one of the second color photoresist columns and between two adjacent third color photoresist units within a same one of the third color photoresist columns, and is not contiguously disposed between the two adjacent first color photoresist units within the same one of the first color photoresist columns, and
the first filling part has a same material as the first color photoresist units, and the second filling part has a same material as the second color photoresist units.
