Abstract
PURPOSE: To provide a chemically and thermally stable nematic liquid crystal compsn. having a wide liquid crystal temp. region from low temp. to high temp. by mixing a phenylcyclohexane derivative with a biphenyl-cyclohexane derivative and a terphenyl derivative.
CONSTITUTION: A cpd. of formula I, e.g. p-propyl-cyclohexyl-p'-cyanobenzene is mixed with a cpd. of formula II, e.g. p-heptyl-cyclohexyl-p'-cyanobiphenyl and a cpd. of formula III, e.g. p-heptyl-p'-cyanoterphenyl to provide a nematic liquid crystal compsn. To the compsn. may be added p-alkoxy-p'-cyanobiphenyl. This compsn. has positive dielectric anisotropy, and it is applicable to a twist nematic liquid crystal display cell, a guesthost effect cell using dichroism of coloring matter or other field effect type cell.
