Abstract
PURPOSE: To provide a chemcially stable white nematic liquid crystal compsn. with low viscosity and positive dielectric anisotropy which compsn. is based on a mixt. of a cyclohexane ester type cpd. and a cyano ester type cpd., and can be driven at low voltage.
CONSTITUTION: A cyclohexane ester type cpd. of formula I, e.g. p-butyl-cyclohexylcarboxylic acid-p'-etoxy-phenyl ester is mixed with a cyano ester type cpd. of formula II, r.g. p-ethyl-benzoic acid-p'-cyanophenyl ester in a ratio, e.g. of 85:15 by wt. to provide a nematic liquid crystal compsn. In case this compsn. is applied to a display device, it can be used effectively in a guest-host type display device using a polygenetic dye as well as in an FE type display device the display of which is carried out by sealing the compsn. in a liquid crystal cell with twist orientation and applying voltage to the cell.
