wherein the plurality of first concave-convex structures each is provided with an edge parallel to the column direction and an edge perpendicular to the column direction;
wherein a side of the orthographic projection of the at least one of the plurality of data lines on the substrate facing away from the orthographic projections of sub-pixels electrically connected with the at least one of the plurality of data lines has a plurality of second concave-convex structures; and
wherein for a same data line, protrusions of the plurality of first concave-convex structures and recesses of the plurality of second concave-convex structures are arranged correspondingly, and recesses of the plurality of first concave-convex structures and protrusions of the plurality of second concave-convex structures are arranged correspondingly.

2. The display substrate according to claim 1 , wherein at least one of the first concave-convex structures and the second concave-convex structures is integrally formed along with the data line.

3. The display substrate according to claim 1 , wherein for a same data line, distances between orthographic projections of centers of any two adjacent recesses in the plurality of first concave-convex structures on the substrate are equal; and
for a same data line, distances between orthographic projections of centers of any two adjacent recesses in the plurality of second concave-convex structures on the substrate are equal.

4. The display substrate according to claim 3 , wherein orthographic projections of at least one of the first concave-convex structures and the second concave-convex structures on the substrate form at least one of: a rectangular waveform pattern, or a fishbone pattern.

5. The display substrate according to claim 4 , wherein orthographic projections of the plurality of second concave-convex structures on the substrate have a same pattern as orthographic projections of the plurality of first concave-convex structures on the substrate.

6. A display panel, comprising:
