1. A touch display device comprising: a display panel including a plurality of subpixels and a plurality of touch electrodes overlapping one or more of the plurality of subpixels; and a touch driving circuit configured to supply a touch driving signal including a plurality of pulses to one or more of the plurality of touch electrodes, wherein the touch driving circuit is configured to output respective touch driving signals having different numbers of pulses in at least two sensing sub-periods in each of at least one touch sensing period in one frame period that includes the at least one touch sensing period and at least one display period, the at least two sensing sub-periods being defined such that any display period is not interposed between the at least two sensing sub-periods within each of the at least one touch sensing period in one frame period, wherein two or more touch electrodes among the plurality of touch electrodes are organized as one sensing unit, wherein when a touch is applied to a first sensing unit among at least two sensing units, the at least two sensing sub-periods are adjusted such that a length of a second sensing sub-period among the at least two sensing sub-periods during which the touch driving signal is supplied to a second sensing unit to which a touch is not applied is less than a length of a first sensing sub-period during which the touch driving signal is supplied to the first sensing unit, and wherein the at least one display period is increased by a reduced length of the second sensing sub-period such that an entire display period allocated for display driving in one frame period is increased relative to the reduction of an entire touch period allocated for touch sensing in one frame period.
