Abstract
The disclosure discloses a touch display panel and a touch display device. The touch display panel includes a cathode and a number of touch electrodes, wherein an interior of at least one touch electrode is hollowed out to reduce a relative area between the cathode and the touch electrode. The relative area between the touch electrode and the cathode of the touch display panel may be reduced by hollowing out the interior of at least one touch electrode, thereby reducing the inductive capacitance between the touch electrode and the cathode.
