ABSTRACT:
A plasma addressed display is intended to improve structures of electrodes and barrier ribs for stabilizing the discharge characteristics and enhancing the yield and the image quality. The plasma addressed display has a flat panel structure in which a display cell is laminated on a plasma cell. The plasma cell has discharge channels sequentially arranged along the scanning direction. The display cell is joined to the plasma cell, and it has signal electrodes sequentially arranged in the direction perpendicular to the scanning direction, and liquid crystal in contact with the signal electrodes. The plasma cell has a lower substrate joined to the display cell side, pairs of anode electrodes and cathode electrodes disposed in discharge channels, and barrier ribs formed on the substrate so as to partition the discharge channels from each other. The cathode electrode is positioned at an approximately central portion of one discharge channel partitioned by the two adjacent barrier ribs, and the corresponding anode electrode is brought in contact with one, positioned on the downstream side of the scanning direction, of the two adjacent barrier ribs.
