Abstract
A plasma-addressed liquid crystal display device capable of high-speed drive and improved viewing characteristic is composed of a liquid crystal cell structure and plasma cell structure stacked with each other. The liquid crystal cell structure is formed by sandwiching a liquid crystal having a spontaneous polarization between a first transparent substrate having therein transparent electrode stripes and an alignment film covering the electrode stripes, and a dielectric sheet having thereon an alignment film. The plasma cell structure is formed of a second transparent substrate having thereon cathode stripes and anode stripes disposed alternately with a spacing therebetween, stacked via stripe-shaped partitions disposed along the anode stripes onto the dielectric sheet so as to form plasma channels between the partitions filled with an ionizable gas sealed up therein.
