Zusammenfassung:	Embodiments of the present disclosure relate to a touch display device, a data driving circuit, and a touch sensing method. By sensing multiple data lines simultaneously using gate signals for display as touch driving pulses, it is possible to provide touch sensing without having a separate touch electrode for touch sensing and touch driving pulses. The touch sensing method includes outputting gate signals sequentially having a pulse section including two or more pulses to gate lines, by a gate driving circuit; outputting an image data voltage to data lines, by a source driving circuit; sensing the data lines by combining every N (N is a natural number of 2 or more) data lines or sensing a plurality of reference voltage lines by combining every N reference voltage lines, by a sensing circuit; and determining a touch or a touch coordinate, based on sensing values obtained by sensing of the sensing circuit.
