1. A display substrate comprising:
a first base substrate;
a plurality of first signal lines on a side of the first base substrate, wherein the plurality of first signal lines extend along a first direction and are arranged along a second direction, and the first direction and the second direction intersect with each other;
a plurality of second signal lines on the same side of the first base substrate as the plurality of first signal lines, wherein the plurality of second signal lines and the plurality of first signal lines are arranged in different layers, and the plurality of second signal lines extend along the second direction and are arranged along the first direction;
a plurality of pixel electrodes on a side, facing away from the first base substrate, of layers where the plurality of first signal lines and the plurality of second signal lines are located, wherein orthographic projections of the plurality of pixel electrodes on the first base substrate are within areas defined by intersections of orthographic projections of the plurality of first signal lines on the first base substrate and orthotropic projections of the plurality of second signal lines on the first base substrate;
a plurality of first light-shielding structures on a side, facing away from the first base substrate, of a layer where the plurality of pixel electrodes are located, wherein the plurality of first light-shielding structures extend along the second direction and are arranged along the first direction, orthographic projections of the plurality of first light-shielding structures on the first base substrate are within orthographic projection of a gaps between columns of pixel electrodes extending in the second direction on the first base substrate, the orthographic projections of the plurality of first light-shielding structures on the first base substrate and the orthographic projections of the plurality of second signal lines on the first base substrate have areas that do not overlap with each other.
