ABSTRACT:
A swallow-tail-shaped liquid crystal compound of the following general formula (1), ##STR1## wherein A is --O--, --COO-- or a single bond (--), m is an integer of 4 to 12, and n is an integer of 2 to 4.
The above swallow-tail-shaped liquid crystal compound of the present invention is a novel achiral anti-ferroelectric liquid crystal and can be converted to an optically active anti-ferroelectric liquid crystal by mixing it with an optically active compound as a chiral dopant.
