ABSTRACT:
A plurality of signal electrodes D arranged in parallel to each other are formed on a major surface of a first substrate 4. A second substrate 6 is opposed to the first substrate. A plurality of plasma electrodes 7 arranged in parallel to each other and intersecting the signal electrodes D are printed on a major surface of the second substrate 6. In addition, an opaque insulating striped pattern 8 is printed so as to intersect and overlap with the plasma electrodes 7. A liquid crystal layer 5 is sandwiched between the first and second substrates 4 and 6. Further, a plasma chamber 10 having consecutive spaces is formed between the liquid crystal layer 5 and the second substrate 6, and filled with an ionizable gas. The gap space of the plasma chamber 10 can be controlled on the basis of the film thicknesses of the plasma electrodes 7 and the striped pattern 8. The gas is selectively ionized by discharge generated between the two adjacent plasma electrodes 7. The liquid crystal layer 5 positioned at the intersections between the signal electrodes D and the discharge regions is driven with the discharge regions (at which the ionized gas is localized) as the scanning unit. The plasma electrodes 7 are formed by a printed thick film and therefore the electric resistance thereof is low.
