Beschreibung
Zusammenfassung:	A liquid crystal display device (1) in accordance with the present invention includes a first common electrode (11) and a second common electrode (12) in each pixel region of a display panel. The device (1) further includes delay circuit (A and B) for delaying the timings of polarity reversals of a first common electrode signal and a second common electrode signal which are respectively input to the first common electrode (11) and the second common electrode (12), said delaying being performed when the first common electrode signal and the second common electrode signal are subjected to respective polarity reversals in each horizontal scan period. The present invention thus provides a liquid crystal display device which, in a display device with wide viewing angle characteristics, lowers peak inrush current which is generated when the common electrode signal (common electrode voltage) is subjected to a polarity reversal.
