Abstract
A touch display panel and a touch display device are provided, relate to the field of display technology. In an embodiment, the touch display panel includes a plurality of first touch electrode units and a plurality of second touch electrode units. In an embodiment, each of the first touch electrode units includes first touch electrodes and first connection portions alternately arranged in a first direction. In an embodiment, each of the first touch electrodes includes at least one first touch electrode sub-unit that includes a plurality of first electrode sub-groups. In an embodiment, each of the first electrode sub-groups includes at least one first sub-electrode. In an embodiment, in each of the at least one first touch electrode sub-unit, the first sub-electrodes of two adjacent first electrode sub-groups have gradually increasing lengths and gradually decreasing widths in a direction from one of the first connection portions closest to the first touch electrode sub-unit to the first touch electrode.
