<p>PURPOSE: A touch display device and a driving method thereof are provided to accurately determine a touch occurrence and a position by minimizing a noise deviation per sub frame period. CONSTITUTION: A touch panel is equipped with driving lines and sensing lines which intersect mutually. A drive line scanning unit (101) successively supplies a driving signal to the driving lines. A sensing signal leading unit (102) classifies the touch panel into touch areas, reads sensing signals which are detected from sensing lines which are positioned in the corresponding touch area during a sub frame period, and reads a sensing signal which is detected from a sensing line which is positioned in a previous touch area. A touch control unit (103) detects a noise deviation based on a difference between sensing signals which are detected twice from a same sensing line during the sub frame periods and corrects the sensing signals.
