Claim 0:
1. A touch display device, comprising:
a touch display panel including touch electrodes, data lines, gate lines, sensing lines, and sub-pixels;
a data driving circuit connected to the data lines;
a gate driving circuit connected to the gate lines; and
a touch sensing circuit configured to output a touch driving signal to at least one touch electrode among the touch electrodes through at least one corresponding sensing line among the sensing lines,
wherein a first driving signal is configured to be applied to at least one of the gate lines while the touch driving signal is output to the at least one touch electrode, and
wherein the first driving signal has a same frequency as the touch driving signal and has a phase difference from the touch driving signal.
