ABSTRACT:
An electro-optical device applied as an image display device includes a first substrate having a plurality of non-overlapping first electrodes on a major surface thereof; and a second substrate opposed to the first substrate and having a plurality of non-overlapping second electrodes on a major surface thereof wherein the second electrodes are disposed substantially perpendicular to the first electrodes. This device further includes an electro-optical material layer disposed between the first and second electrodes; and a discharge chamber disposed between the electro-optical material layer and the second substrate, and filled with an ionizable gas, the discharge chamber having a plurality of scanning units, the scanning units being divided by partition walls formed by a printing process. By formation of grooves by the printing process, the difficult process of etching of grooves or formation of electrodes in the grooves is unnecessary, and the manufacturing is easy. This is advantageous to implementation of large display screens or miniaturization.
