1. A touch layer group, having a touch region and a peripheral region;
the touch layer group comprising:
a plurality of first touch electrodes and a plurality of second touch electrodes that are located in the touch region;
a plurality of first touch lines electrically connected to the plurality of first touch electrodes, respectively; the plurality of first touch lines each extending to the peripheral region;
a plurality of second touch lines electrically connected to the plurality of second touch electrodes, respectively; the plurality of second touch lines each extending to the peripheral region; and
a shielding line located in the peripheral region and located between a first touch line and a second touch line that are adjacent to each other; wherein the shielding line includes at least one first line segment and at least one second line segment; each second line segment includes a plurality of shielding sub-lines, and the plurality of shielding sub-lines of each second line segment each extend in a same direction and are spaced apart from one another; a plurality of shielding sub-lines of a second line segment are all electrically connected to a first line segment, and a width of a region where the plurality of shielding sub-lines of the second line segment are located is greater than a width of the first line segment, wherein
the touch region includes a first edge the peripheral region includes a first fan-out region connected to the first edge of the touch region, a bending region located on a side of the first fan-out region away from the touch region, and a lead-out region located on a side of the bending region away from the first fan-out region;
the at least one second line segment includes a second second line segment, the lead-out region is provided with the second second line segment therein, and all shielding sub-lines of the second second line segment each extend towards a direction far away from the touch region.
