  The carboxylic acid ester compound of the invention is represented by the following formula [I]: ##STR1## wherein R is an alkyl group of 3-20 carbon atoms; n is 0 or 1; at least one of A.sup.1, A.sup.2 and A.sup.3 is a group having tetralin structure, and the residual groups of A.sup.1, A.sup.2 and A.sup.3 are each independently a group having specific aromatic cyclic structure such as a phenylene group and a biphenyl group; Y.sup.1 and Y.sup.2 are each independently a group selected from the group consisting of --COO--, --CH.sub.2 CH.sub.2 -- and --CH.sub.2 O--; Q.sup.1 is a group selected from the group consisting of --CH.sub.3, --CF.sub.3, --C.sub.2 H.sub.5 and --C.sub.2 F.sub.5 ; and q is an integer of 4 to 12. This carboxylic acid ester compound may be used as an antiferroelectric liquid crystal material, and also be used as a liquid crystal composition by using other liquid crystal material in combination. A liquid crystal element which is formed by filling the carboxylic acid ester compound in a gap between two substrates opposite to each other shows excellent properties required for antiferroelectric liquid crystal elements, for example, high speed switching.
