Touch display panel and touch display device
Disclosed are a touch display panel and a touch display device. In a touch display panel and a touch display device, a shielding pattern is arranged between a data link line and a touch link line in a non-active area of the touch display panel, and a signal corresponding to the touch driving signal is applied to the shielding pattern. Parasitic capacitance between the data link line and the touch link line is prevented in order to reduce noise on the touch sensing signal caused by voltage fluctuation on the data link line. Accordingly, it is possible to reduce the influence of display driving on touch sensing, thereby improving touch sensing during display driving.
