1. A display substrate, comprising:
a base substrate;
a plurality of sub-pixel groups, arranged on the base substrate along a row direction and a column direction; and
first spacers, second spacers, and third spacers,
wherein each of the plurality of sub-pixel groups comprises a first sub-pixel, a second sub-pixel, and a third sub-pixel,
in one row of sub-pixel groups, each of the first spacers is located between the first sub-pixel and the second sub-pixel which are adjacent to each other, each of the second spacers is located between the second sub-pixel and the third sub-pixel which are adjacent to each other, the third spacer is located between the third sub-pixel and the first sub-pixel which are adjacent to each other, and a number of the first spacers, a number of the second spacers, and a number of the third spacers are approximately equal to one another;
in one row of sub-pixel groups, one first sub-pixel, one second sub-pixel, one third sub-pixel pair and one fourth sub-pixel are arranged between every two adjacent spacers among the first, second and third spacers, wherein the fourth sub-pixel is one of the first sub-pixel, the second sub-pixel and the third sub-pixel pair.
