1. A display substrate, comprising a base substrate and a pixel define layer disposed on the base substrate, wherein the pixel define layer comprises first define layers and a second define layer, a printing region is formed on the base substrate between the first define layers, and the second define layer is disposed on the printing region and divides the printing region into two sub-printing regions, and a height of the first define layers is greater than a height of the second define layer in a direction perpendicular to the base substrate; wherein in the direction parallel to the base substrate, the first define layer is regular hexagonal, the printing region is regular hexagonal, and the two sub-printing regions are symmetrically disposed at two sides of the second define layer;
wherein sub-printing regions in at least two of the adjacent printing regions are combined to form a pixel region; wherein in the direction parallel to the base substrate, the pixel region is triangular.
