1. A touch display device comprising:
a substrate comprising a display area and a non-display area located outside of the display area;
at least one subpixel disposed in the display area, the at least one subpixel including a display anode electrode, an emission layer and a display cathode electrode;
a display driving transistor disposed in the display area, the display driving transistor being configured to drive the display anode electrode;
a touch electrode disposed in the display area;
a touch driving transistor disposed in the display area and configured to drive the touch electrode, the touch driving transistor including a first active layer, a first source electrode, a first drain electrode and a first gate electrode; and
a control transistor configured to control turn-on and turn-off operations of the touch driving transistor, the control transistor including a second active layer, a second source electrode, a second drain electrode and a second gate electrode,
wherein the second source electrode or the second drain electrode of the control transistor is electrically connected to the first gate electrode of the touch driving transistor,
the second drain electrode or the second source electrode of the control transistor is electrically connected to a first switching signal line, and
the second gate electrode of the control transistor is electrically connected to a driving signal line.
