Abstract
A liquid crystal display wherein display is performed based on the fact that an a.c. voltage is applied to a liquid crystal layer when a switching element establishes a connection between a display electrode and a common electrode, and the a.c. voltage is not applied to the liquid crystal layer when the switching element releases the connection between the display electrode and the common electrode. A state of the switching element changes from connection between the display electrode and the common electrode to release of the connection under a condition that respective voltages of an opposite electrode, the display electrode, and the common electrode are made substantially the same, the condition being produced by stopping an a.c. voltage applied to the opposite electrode.
