Abstract:
An electro-optical device comprising:a first substrate having a plurality of substantially parallel non-overlapping first electrodes on a major surface thereof; a second substrate opposed to the first substrate and having a plurality of substantially parallel nonoverlapping second electrodes on a major surface thereof and the second electrodes extending in a different direction than the first electrodes so that they cross closely adjacent to each other; an electro-optical material layer disposed in contact with the first electrodes of the first substrate; a discharge chamber formed between the electro-optical material layer and the second substrate and filled with an ionizable gas, and means for providing discharge regions to define scanning units in the discharge chamber, the discharge regions being produced by selectively effecting ionization of the ionizable gas so that the scanning units are defined substantially in parallel to each other, the second electrodes being arranged so that the discharge region for all of the scanning units is formed as an open cell structure having a continuous space in the direction of scanning and over the entire lengths of the second electrodes; and scanning means for interlaced scanning of n:1, where n is an integer &diam;1 and a spread of a respective discharge region is set so it spreads to a size which is n times as large as the scanning unit.
