Plasma addressing electro-optical device having invertor circuit connected to anodes

Abstract

A plasma addressing electro-optical device which can be driven at a comparatively low voltage is disclosed. A plurality of signal electrodes are formed on an inner surface of an upper glass substrate. A plurality of plasma electrodes as anodes and cathodes are formed on an inner surface of a lower glass substrate and extend perpendicularly to the signal electrodes. A liquid crystal layer is filled between the upper glass substrate and an intermediate dielectric sheet. A plasma chamber is provided between the dielectric sheet and the lower glass plate, and ionizable gas is enclosed in the plasma chamber. The gas is selectively ionized by discharge between the cathodes and the anodes, and taking the discharge regions, in which the ionized gas exists locally, as scanning units, the liquid crystal layer positioned at intersecting positions between the signal electrodes and the discharge regions is driven. A driver circuit for such driving includes an invertor circuit which inverts an image signal to be applied to the signal electrodes and a potential to the anodes at a time with reference to a potential of a substantially middle level of a driving voltage for the signal electrodes.
