<p>The present invention provides a touch display device which implements the display on a screen and the recognition of a touch action using the time division technique. The present invention includes a timing controller which provides a display control signal and a touch control signal to perform the display and the touch recognition using the time division method; a display panel in which a plurality of pixels are driven by source driving signals and gate driving signals for the display and provide a connection point for the touch recognition, and which performs the touch recognition through changes in signals applied to the connection point; a source driver which receives source control signals included in the display control signal and provides the source driving signals to the pixels; a gate driver which receives gate control signals included in the display control signal and provides the gate driving signals to the pixels; and a touch driving circuit which receives the touch control signal, provides a touch driving signal, and senses changes in the signal following the touch recognition. In response to the touch recognition, at least one among the source driver and the gate driver has floated output terminals.
