ABSTRACT:
A plasma addressed liquid crystal display device having a flat panel structure where a liquid crystal cell is superposed on a plasma cell. The liquid crystal cell includes a front substrate with data electrodes arranged in columns, an intermediate substrate bonded to the front substrate via a predetermined gap, and a liquid crystal filled in the gap. The plasma cell includes a rear substrate joined to the intermediate substrate via a predetermined space, and discharge channels formed in the space and arranged in rows. The intermediate substrate is dimensionally so set as to include an overlapping planar region of the front substrate and the rear substrate which are different in shape from each other. Further a plurality of barrier ribs for prescribing the space dimension in the plasma cell are existent between the intermediate and rear substrates over the planar region.
