Abstract

PURPOSE: To provide a phase transition type positive dielectric anisotropic liquid crystal compsn. which can be driven at a low voltage, by mixing a plurality of nematic liquid crystals having specified physical properties such as double refractive index, dielectric anisotropy, torsional modulus, etc.
CONSTITUTION: Nematic liquid crystals of formulaIsuch as 4-ethoxyphenyl-4- propyl cyclohexyl-carbonate, of formula II such as 4-cyanophenyl-4-ethyl benzoate, and of formula III such as 5-ethyl-2-(4'-cyanophenyl)-1,3-dioxane are mixed together. In the above formulasI, II and III, R1, R2, R3, R4 are each a 1W8C straight-chain alkyl, and the group of formula IV is a cyclohexane ring. Further, compds. of formulas V, VI and VII (wherein R5, R6, R7, R8, R9 are each a 1W5C straight-chain alkyl), an optical active material, a dichroic coloring matter, etc. may be blended with the above liquid crystal compsn.
