There is provided a liquid crystal compound represented by the following general formula (I), a liquid crystal composite including at least one kind of above liquid crystal compound and a liquid crystal device in which the liquid crystal composite is disposed between a pair of electrode substrates. ##STR1## In the above formula (I), R.sub.1 is a straight chain alkyl having 1-12 carbon atoms. R.sub.2 is a straight chain or branched chain alkyl, which may have a substituted radical, having 1-18 carbon atoms and in which one or more than two methylene, which do not adjoin, may be substituted by --Y--, ##STR2## --CH.dbd.CH--, or --C.vertline.C--. Y is O or S. A is --A.sub.1 -- or --A.sub.1 --A.sub.2 --, and B is --B.sub.1 -- or --B.sub.1 --B.sub.2 --. A.sub.1, A.sub.2, B.sub.1, and B.sub.2 each is selected from ##STR3## and a single bond. Z is hydrogen, halogen, cyano or methyl. X.sub.1 is a single bond when A is a single bond and is --CH.sub.2 O--, ##STR4## in other cases. n is 0 or 1, ##STR5## --OCH.sub.2 -- or --CH.sub.2 O, and D is a single bond, ##STR6## and *designates an asymmetric carbon atom.
