摘要

PROBLEM TO BE SOLVED: To appropriately reverse a polarity of a voltage applied to an electrooptical device without needing any electric discharging operation in a configuration where a potential of a common electrode is varied. SOLUTION: A reversal potential LCCOMX sequentially varied from one of a high-side potential VH and a low-side potential VL to the other by unit period F is supplied to a reversal potential line 24. A pixel circuit PIX includes a liquid crystal element 50 including a pixel electrode 52 and a common electrode 54, and a first control switch TC1 interposed between the pixel electrode 52 and the reversal potential line 24. A common potential LCCOM obtained by reversing a potential of the reversal potential LCCOMX is supplied to the common electrode 54. A driving circuit controls the first control switch TC1 to an ON state during a reversal period W where the common potential LCCOM is varied after application of a voltage VA to the liquid crystal element 50, and the first control switch TC1 to an OFF state during a reversal period W where the common potential LCCOM is varied after application of a voltage VB (VB
