ABSTRACT:
A plasma addressed liquid crystal display (10) uses a liquid crystal material (18) having a low .DELTA..epsilon., .epsilon..sub..perp., and .DELTA.n, resulting in reduced sensitivity to cross talk, reduced operating voltage, and improved resistance to the deleterious electrochemical effects of direct current biases. Liquid crystal layers of low .DELTA..epsilon., .epsilon..sub..perp., and .DELTA.n materials exhibit lower capacitance, which increases the threshold voltage and reduces the saturation voltage to achieve reduced sensitivity to crosstalk and a lower operating voltage.
