1. A touch display panel, comprising a touch electrode wiring layer and a signal transmission wiring layer, wherein the touch electrode wiring layer comprises a plurality of touch electrode repetition units, each of the touch electrode repetition units comprises a plurality of touch sub-units and a plurality of connection wires, the plurality of touch sub-units comprise a part of the touch sub-units extending in a first direction and a part of the touch sub-units extending in a second direction, and two adjacent columns of the touch sub-units extending in the second direction are electrically connected via the connection wires;
wherein the signal transmission wiring layer comprises a plurality of signal transmission wires extending in the second direction; wherein an orthographic projection of each of the signal transmission wires on the touch electrode wiring layer is located between two adjacent columns of the touch sub-units, and the orthographic projection of each of the signal transmission wires on the touch electrode wiring layer at least partially overlaps with one of the connection wires;
wherein in each of the touch electrode repetition units, the connection wires distributed in the first direction are disposed in a misaligned manner in the second direction;
wherein in each of the touch electrode repetition units, two of the connection wires adjacent to each other in the first direction are disposed in a misaligned manner in the second direction;
wherein in each of the touch electrode repetition units, two adjacent columns of the touch sub-units extending in the second direction are electrically connected via at least one of the connection wires;
wherein in each of the touch electrode repetition units, only one of the connection wires is provided in one row of touch sub-units extending in the first direction.
