<p>PURPOSE:To prevent a DC component from being applied to a liquid crystal, and to improve reliability and a picture quality of the liquid crystal display device by making an average level of potential of the picture element capacity coincide exactly with a counter electrode voltage of the picture element capacity. CONSTITUTION:The driving circuit is provided with a voltage transition circuit 6 for allowing an auxiliary capacity counter electrode voltage VS applied by a counter electrode power source circuit 5 to fall temporary, when a gate signal VG of a thin film transistor Q rises, and returning this auxiliary capacity counter electrode voltage VS to an original state, when the gate signal VG falls.</p> |
