Abstract
A liquid crystal display device is disclosed comprising a display part, a scanning line driving circuit, a signal line driving circuit, a counter electrode driving circuit for providing counter electrodes with a counter electrode driving signal reversed in phase from a signal line driving circuit, an auxiliary capacitance having one end connected to an output end of each of switching elements, and an auxiliary capacitance line driving circuit for driving a plurality of auxiliary capacitance lines arranged in rows and has ends of such auxiliary capacitances in each row commonly connected thereto, wherein the auxiliary capacitance line driving circuit is adapted to apply a first voltage to the auxiliary capacitance lines for a first half cycle of the counter electrode driving signal and apply a second voltage thereto for a (p+½)th cycle after the first period of the counter electrode driving signal where p is 0 or a natural number, said auxiliary capacitance line driving circuit making the auxiliary capacitance line in a floating condition after said (p+½) th cycle during the remaining holding time.
