Abstract

PURPOSE: To provide a liquid crystal compn. contg. a specific 4-(4-R-cyclohexyl) benzonitrile, such a cyclohexyl carboxylate and such a 4-cyanopheny1-4'-R-benzoate which compsn. has good temp. characteristics, responds in a short time, and can be driven at low voltage.
CONSTITUTION: The liquid crystal compsn. contains more than 30% of a 4-(4-R- cyclohexyl)benzonitrile of formula I( where R: 3W8 C alkyl), a 4-X-phenyl -4'-R- cyclohexyl carboxylate of formula II(where each of R and X: 3W8 C alkyl or alkoxy), and 10W30% of a 4-cyanophenyl-4'-R-benzoate of formula and X: 3W8 C alkyl or alkoxy), and 10W30% of a 4-cyanophenyl-4'R-benzoIII(where R: 3W8 C alkyl). This nematic compsn is useful for a twisted nematic type display device, has positive dielectric anisotropy, and assumes a white color.
