Patent

CA 2353760

A supertwisted nematic liquid crystal display having a twist angle of 180 to 270°C and comprising: a pair of substrates each having an orientation-controlling layer and a transparent electrode; a liquid crystal layer comprising a liquid crystal composition, which is sandwiched by the substrates; and at least one polarizing sheet provided on at least one of the substrates, wherein the liquid crystal composition comprises: at least one compound represented by formula (I): Image and at least one compound represented by formula (II): Image and wherein said liquid crystal composition has a nematic- isotropic phase transition temperature of 75 to 150°C and a refractive index anisotropy (.DELTA.n) of 0.07 to 0.25. The symbols in formulae (I) and (II) are defined in the specification.
