1. A touch substrate, comprising: a base, a first touch layer and a second touch layer on the base, and an interlayer insulation layer between the second touch layer and the first touch layer; wherein
the first touch layer comprises a plurality of first touch electrodes and a plurality of touch signal lines arranged side by side along a first direction and extending in a second direction; and
the second touch layer comprises a plurality of second touch electrodes arranged side by side along the second direction, each of the second touch electrodes extends in the first direction and is connected to at least one of the touch signal lines through a first connection via penetrating through the interlayer insulation layer; and wherein
the first touch layer further comprises at least one shielding electrode extending in the second direction and arranged between at least part of the first touch electrodes and at least part of the touch signal lines, and wherein
at least one shielding electrode is disposed between every two adjacent first touch electrodes; and
each touch signal line comprises a first side and a second side opposite to each other in the first direction; and the shielding electrode is disposed between the first touch electrode and only one of the first side or the second side of the touch signal line.
