PROBLEM TO BE SOLVED: To prevent the fixation of a reverse twist oriented fault of liquid crystal and to make an excellent display with high surface pressure resistance possible by providing a period supplying a data voltage to respective drain lines and a period supplying a voltage of a potential equal to a common electrode in every scan field. SOLUTION: A liquid crystal panel is provided with a common voltage generation circuit, a drain voltage (data signal) generation circuit, a gate voltage (scan signal) generation circuit and a control circuit, and the control circuit controls the respective circuits so as to become a common signal Vcom, a drain signal Dn (case of black display) and gate signals gate gate 1 - gate 220. When such a liquid crystal display device is driven at 60 Hz, the scan time of the gate signals gate 1-gate 220 for every field becomes 13.93 m sec, and an excess period T=2.74 m sec of a second half of every field is the period not contributing to a display. A reset voltage is supplied to respective drain lines 4 in the period T.
