A touch display device, a driving circuit, and a driving method are provided. An image defect which occurs when display driving and touch driving are simultaneously executed can be reduced by performing control such that a voltage level of a touch electrode driving signal (TDS) varies in a section other than a high-level period (Pon) of an ON-clock signal (ON_CLK) and/or a high-level period (Poff) of an OFF-clock signal (OFF_CLK).
