Touch display device and touch sensing circuit

A touch display device may include 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. A first driving signal may be configured to be applied to at least one of the data lines while the touch driving signal is output to the at least one touch electrode. The first driving signal may have a same frequency as the touch driving signal and may have a phase difference from the touch driving signal.
