Abstract

A plasma addressed electro-optical device comprising a first substrate having a plurality of first electrodes arranged substantially in parallel to each other on a major surface thereof; a second substrate opposed to the first substrate and having a plurality of second electrodes arranged substantially in parallel to each other on a major surface thereof; an electro-optical material layer positioned between the first and second substrates; and a discharge chamber formed between the electro-optical material layer and the second substrate and containing an ionizable gas. The second electrode has a plurality of barrier ribs periodically disposed thereon, and the first and second electrodes are so arranged as to be spaced apart in the vertical and horizontal directions, respectively. And each of the barrier ribs is substantially the same in width as the second electrode. Since the width of each electrode is reducible to be equal to that of the barrier rib, both definition and fineness can be enhanced in the device.
