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. |

DETAILED DESCRIPTION With the above-mentioned problems with such prior arts in view, the present invention has been proposed, and its object is to provide an electro-optical device applied as an image display device that is simple to manufacture and suitable for implementation as a large display surface and with highly miniaturized components.
To attain the above-described and other objects, there is provided in accordance with this invention an electro-optical device comprising: a first substrate having a plurality of non-overlapping first electrodes on a major surface thereof; a second substrate opposed to the first substrate and having a plurality of non-overlapping second electrodes on a major surface thereof, the second electrodes being disposed substantially perpendicular to the first electrodes; 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 printing.
There may be also provided an addressing structure comprising: a substrate having a plurality of electrodes on a major surface thereof; a dielectric material layer opposed to the substrate; and an ionizable gas filled between the substrate and the dielectric material layer, the ionizable gas defining a discharge region which provides scanning units divided by partition walls formed by printing.
In the image display device of this invention, partition walls dividing the discharge area every scanning unit are formed by the printing process.
The printing process is a very simple technique, and permits formation of a fine pattern.
Thus, the productivity and/or working efficiency can be improved to a higher degree as compared to the groove forming method.
Further, since the second electrodes for discharge are formed on a flat substrate, etching process is also simple, and the distance between electrodes can be controlled with high accuracy
