1. A display substrate, comprising:
a base substrate;
a pixel defining layer, located on the base substrate and comprising a plurality of openings; and
a spacer, located on a side of the pixel defining layer away from the base substrate,
wherein the plurality of openings comprise a plurality of opening groups, the plurality of opening groups comprise a plurality of opening group rows, each of the opening group rows extends along a first direction, and the plurality of opening group rows are arranged along a second direction, two adjacent opening group rows are offset from each other in the first direction,
each of the opening groups comprises a first opening and a second opening that are sequentially disposed along the first direction, the plurality of opening group rows comprise a first opening group row and a second opening group row that are adjacent in the second direction, the spacer is located between the first opening of the first opening group row and the second opening of the second opening group row, an orthographic projection of the first opening on the base substrate comprises a first long edge, and an orthographic projection of the second opening on the base substrate comprises a second long edge, the first long edge is parallel to the second long edge, an extension line of the first long edge is misaligned from an extension line of the second long edge,
an orthographic projection of the spacer on the base substrate comprises a third long edge, and an angle between an extension line of the third long edge and the extension line of the first long edge ranges from 20 degrees to 70 degrees, the orthographic projection of the first opening on the base substrate comprises a first short edge, and the length of the third long edge is greater than a length of the first short edge.
