During a sustain period, a gate-source voltage of the switching transistor can be increased, and accordingly an influence due to the leakage current can be minimized, thereby preventing image deterioration. Further, since capacitance of the sustain capacitor can be reduced so that power consumption of the LCD can be reduced.
