摘要：
In a plasma addressed liquid crystal display panel comprising a channel substrate, a cover sheet, a layer of twisted nematic liquid crystal material, an upper substrate, and an array of electrodes on the lower surface of the upper substrate, ##EQU1## where V.sub.x is the voltage that will turn a simple TN liquid crystal cell from the off state to X% transmissive in a normally black mode, d.sub.TD is the thickness of the cover sheet, d.sub.LC is the thickness of the liquid crystal layer, .epsilon..sub.TD is the dielectric constant of the cover sheet, .epsilon..sub..perp. is the perpendicular dielectric constant of the liquid crystal material, and .epsilon..sub..parallel. is the parallel dielectric constant of the liquid crystal material, and d.sub.LC .DELTA.n.sub.LC is in the range from about 0.4 to 0.5, where .DELTA.n.sub.LC is the difference in refractive indices for the liquid crystal material.
