Liquid crystal display devide with a twisted alignment state
 A liquid crystal device has a pair of substrates having a plurality of electrodes arranged on facing surfaces thereof, aligning films, rubbed in a predetermined direction, for covering the surfaces of the substrates and the surfaces of the electrodes, a nematic liquid crystal disposed between these aligning films, and a pair of polarizing plates disposed outside the substrates. The liquid crystal device has an optical anistropy .DELTA.n of 0.12 or below, a dielectric ratio .DELTA..epsilon./.epsilon.1 of 1.0 or below, expressed by a ratio of a dielectric anistotropy .DELTA..epsilon. of a dielectric constant in a direction normal to the axes of liquid crystal molecules, and a retardation .DELTA.n.multidot.d of greater than 0.4 .mu.m and less than 1.0 .mu.m, which is expressed by a product of the optical anisotropy .DELTA.n and the thickness d of a liquid crystal layer. The nematic liquid crystal is twised 180.degree. to 270.degree. between the aligning films.
