ABSTRACT:
An antiferroelectric liquid crystal substance represented by the following general formula (1) ##STR1## wherein R represents a straight-chain alkyl group of 6-10 carbon atoms; X represents ##STR2## when X is ##STR3## Y is any of CH.sub.3, CF.sub.3 and C.sub.2 H.sub.5, L is 0 or an integer of 5 to 8, m is 0 or 1, and n is an integer of 1 to 10; when X is ##STR4## Y is any of CH.sub.3, CF.sub.3 and C.sub.2 H.sub.5, and (1) when Y is CH.sub.3, L is 0 or an integer of 5 to 8, m is 0 or 1, and n is an integer of 1 to 10, (2) when Y is CF.sub.3, L is an integer of 5 to 8, m is 1, and n is an integer of 1 to 10 and (3) when Y is C.sub.2 H.sub.5, L is 0, m is 0, and n is an integer of 4-10.
