ABSTRACT:
In a liquid crystal display device in which a twisted nematic liquid crystal layer of positive dielectric anisotropy is sandwiched between two substrates fitted with electrodes and liquid crystal molecule orientation films, and in which the angle of intersection of the liquid crystal molecular alignment directions on the surfaces of the two substrates is .theta. (0.degree.<.theta.<90.degree.) and the cell twist angle is .phi. which is determined to give a uniform twist alignment to the liquid crystal layer by the tilt orientation on the two substrates, the liquid crystal molecule orientation films have a twist angle .omega. which is +.theta.+180.degree. or +.theta.-180.degree. when .phi. is +.theta., and which is -.theta.+180.degree. or -.theta.-180.degree. when .phi. is -.theta., in the state when a voltage applied to the liquid crystal layer is less than a threshold voltage.
