A touch display panel is provided, which includes a touch structure layer. The touch structure layer includes touch signal lines and touch electrodes. The touch electrodes include electrode lines. Each of the touch signal lines includes signal main lines and redundant signal lines disposed on one side of one row of first sub-pixels. Any one of the signal main lines and signal main lines adjacent to one side of the one of the signal main lines are spaced apart by at least two rows of the first sub-pixels, and the one of the signal main lines and signal main lines adjacent to another side of the one of the signal main lines are spaced apart by at least one row of the first sub-pixels.
