Abstract
An object of the present invention is to provide a flat display device which achieves an excellent and stable display even when the periodicity of voltage polarity is switched at the beginning of a frame at the time of driving a signal line while providing a periodicity of every M scanning lines to the voltage polarity of signal lines in each frame. A control circuitcontrols so as to provide a voltage polarity of the final line in the periodicity of every four scanning lines to a signal line prior to driving a signal line corresponding to the first scanning line Y() at the beginning of a frame.
