A touch display device can include first and second touch electrodes spaced apart from each other, a first touch line to which a first touch driving signal is applied, a first touch driving transistor configured to control a connection between the first touch electrode and the first touch line, and a second touch driving transistor configured to control a connection between the second touch electrode and the first touch line. As the first touch driving transistor is turned on, a first touch driving signal can be supplied to the first touch electrode through the first touch line, and as the second touch driving transistor is turned on, the first touch driving signal can be supplied to the second touch electrode through the first touch line.
