Patent ID: 7098885

Claim:
A display device in which a voltage serving as an image signal representing part of an image to be displayed is applied to a capacitive load including a capacitance formed by mutually opposing first and second electrodes, and which has a drive circuit that causes the voltage applied to the capacitive load to reverse polarity periodically, the display device comprising: a common electrode drive circuit for supplying a voltage V COM to the second electrode; an image signal line drive circuit for supplying a voltage signal to the first electrode; a connection switching circuit, when the polarity of the voltage applied to the capacitive load is reversed, for electrically separating the first electrode from the image signal line drive circuit and shorting the first electrode to an electrode providing a voltage level that is equivalent to the voltage supplied to the second electrode during a shorting interval; and wherein during the shorting interval an amplitude of V COM being supplied to the second electrode changes from a first value to a second value at a time when the first electrode is shorted to the electrode providing the voltage level that is equivalent to the voltage supplied to the second electrode.
