1. A touch substrate, comprising a plurality of touch electrodes and a plurality of touch leads;
wherein the touch substrate comprises a touch region and a non-touch region, the plurality of touch electrodes are located in the touch region, and the plurality of touch leads are located in the non-touch region and configured to provide signals for the plurality of touch electrodes;
the touch substrate comprises at least one bending boundary, and the touch substrate is divided into a flat region and a bending region located on at least one side of the flat region;
the touch substrate comprises a first edge, a second edge adjacent to the first edge, and a corner between the first edge and the second edge;
the at least one bending boundary is at least partially located in the touch region and extends to the non-touch region, and the at least one bending boundary substantially extends in an extension direction of the first edge and intersects with the second edge; and
at least one touch lead among the plurality of touch leads comprises: a corner lead located in at least one corner in the touch substrate, and a first lead portion connected with an end of the corner lead; wherein the first lead portion substantially extends in an extension direction of the second edge, and the corner lead is completely located in the bending region and does not overlap the bending boundary;
wherein the first lead portion comprises a first lead layer and a second lead layer which are disposed in a stacked manner, and in a region where the bending boundary overlaps the first lead portion, the second lead layer is electrically connected with the first lead layer.
