Abstract
The present invention is a liquid crystal material including a base crystal material, a compound represented by the following general formula (I) and/or a compound represented by the following general formula (II) ##STR1## (where n is an integer of 0 to 10, m is an integer of 0 to 15, and x is cyano group or halogen).
Claims11
A liquid crystal material, comprising a base liquid crystal material, and a viscosity reducing agent having the formula (I) or formula (II) or both:
- ##STR3## wherein n is an integer of 0 to 10;
- m is an integer of 0 to 15;
- x is a cyano group or halogen;
- and
- wherein the viscosity reducing agent is formulated in a proportion of from about 0.01 to 20% by weight.
A liquid crystal display element, comprising a pair of substrates having an electrode film and a liquid crystal layer interposed between the pair of the substrates which are disposed so that the electrode films face each other, the liquid crystal layer containing a base liquid crystal material, and a viscosity reducing agent having the formula (I) or (II) or both:
- ##STR4## wherein n is an integer of 0 to 10;
- m is an integer of 0 to 15;
- x is a cyano group or halogen;
- and
- wherein the viscosity reducing agent is formulated in a proportion of 0.01 to 20% by weight.
