Abstract
A liquid crystal display (LCD) using a plasma addressing method includes a sequentially arranged face plate, intermediary plate, and rear plate separated from each other by predetermined distances; a liquid crystal portion including a liquid crystal material between said face and intermediary plates for displaying an image in accordance with the arrangement of the liquid crystal material; and a plasma portion formed by sealing a discharge gas between the intermediary and rear plates for rearranging the liquid crystal material by adjusting the discharging state of the discharge gas. The LCD has AC voltage-supply parallel column electrodes on the inner surface of the face plate for supplying a constant frequency AC voltage, data signal-supply anodes on the inner surface of the rear plate for supplying data signals, and line scanning signal-supplying cathodes insulated from and at right angles to the data signal-supply anodes on the inner surface of the rear plate for supplying line scanning signals. A driving method of the display is also provided. Both the liquid crystal portion and the plasma addressing portion can be driven by just one driving IC which reduces manufacturing cost and enhances the display's response.
