1. A display substrate, comprising:
a base substrate;
a first metal signal line layer, located on the base substrate and comprising a plurality of first metal signal lines extending along a first direction, a plurality of metal connection signal lines being comprised between every two adjacent first metal signal lines, and the plurality of metal connection signal lines connecting the two adjacent first metal signal lines;
a metal touch layer, located at a side of the first metal signal line layer away from the base substrate and comprising a plurality of grid lines which are intersected, the plurality of grid lines forming a plurality of grids arranged in an array,
wherein at least a part of each of the plurality of metal connection signal lines is parallel to the plurality of grid lines of the metal touch layer, and in a direction perpendicular to the base substrate, the part of each of the plurality of metal connection signal lines parallel to the plurality of grid lines of the metal touch layer is at least partially overlapped with the plurality of grid lines of the metal touch layer;
each of the plurality of metal connection signal lines is a fold line comprising a first metal connection line segment and a second metal connection line segment connected with each other;
the second metal connection line segment is parallel to the grid lines of the metal touch layer, and in the direction perpendicular to the base substrate, the second metal connection line segment is overlapped with the grid lines of the metal touch layer; and
in the direction perpendicular to the base substrate, an overlapping area between the second metal connection line segment of the metal connection signal line and the grid lines is greater than 50% of an area of the metal connection signal line.
