Abstract: The present disclosure provides a touch display panel or a touch display device and a gate driving circuit included in the touch display panel or the touch display device. The gate driving circuit includes a shift register group outputting scan signals during a display driving period and a dummy shift register group outputting dummy signal during a touch driving period. The gate driving circuit transmits a signal output immediately before a display driving period before a touch driving period ends, through dummy shift registers during the touch driving period such that the signal is used for outputting a first scan signal in the next display driving period. Accordingly, it is possible to prevent output reduction of a scan signal at the boundary between the touch driving period and the display driving period and prevent defect in an image due to the output reduction.
