A ferroelectric liquid-crystalline polymer consisting essentially of at least one repeating unit represented by the following general formula: ##STR1## wherein k is an integer having a value of 2 to 30; R.sup.1 is ##STR2## X is --COO-- or --OCO--; and R.sup.2 is --COOR.sup.3, --OCOR.sup.3 or --OR.sup.3 ; wherein R.sup.3 is ##STR3## wherein each of R.sup.4 and R.sup.5 is independently --CH.sub.3, a halogen atom or --CN; each of m and n is independently an integer having a value of 0 to 10, with the proviso that when R.sup.4 is --CH.sub.3, n is not an integer having a value of 0; p is an integer having a value of 0 or 1; and C marked with * is an asymmetric carbon atom.
