The embodiment of the invention provides a touch display panel and a touch
display device, relates to the technical field of display, and increases the distance between touch
signal lines in a step area. The panel comprises a display area and a non-display area. The non-display area comprises a step area and a non-step area, and the step area comprises a wiring area, a bending area and a functional area; The panel also comprises a
retaining wall which is arranged around the display area in the non-display area; touch electrodes and touch
signal lines, wherein the touch
signal lines extend to the functional area from the non-step area, the routing area and the bending area, the parts, located in the non-step area, of the touch
signal lines are touch routing lines, the touch routing lines are located on the sides, close to the display area, of the retaining walls, and the parts, located in the step area, of the touch
signal lines are touch leads; an electrostatic shielding signal line which is located in the non-display area, wherein the part, extending in the second direction in the step area, of the electrostatic shielding signal line is located on the side, away from the display area, of the
retaining wall, and the second direction is the extending direction of the
retaining wall in the step area.
