Abstract

PURPOSE: To provide a liquid crystal compsn. which can lower a driving voltage and is useful for a liquid crystal display element which utilizes the dielectric dispersion of a liquid crystal, by a method wherein a specified compd. is incorporated into a liquid crystal.
CONSTITUTION: A compd. of formula I wherein R, R1 are 1W8C straight chain alkyl is mixed with a liquid crystal. Examples of the compd. of formula I are the compd. having formulae II and III. Examples of the liquid crystals which can be mixed with compd. of formula I are the compd. of formulae IV and V. The compd. of formula I does not exhibit a liquid crystal phase. But, the molecule thereof is in the form of a rod, and therefore, the compd. of formula I or when it is mixed with another optional liquid crystal causes an orientation and anisotropy similar to those of the liquid crystal. As the compd. of formula I have two cyano groups orienting with an angle of about 60° to the long axis of the molecule, only a small amount of the compd. can impart negative dielectric anisotropy to the liquid crystal when the compd. is mixed with the liquid crystal.
