A ferroelectric liquid-crystalline polymer consisting essentially of at least one repeating unit represented by the following general formula:n wnereinn k is an integer having a value of 2 to 30;n n X is -COO- or -OCO-; and R 2 is -COOR 3 , -OCOR 3 or -OR 3 ; nwhereinn wherein each of R 4 and R 5 is independently -CH s , 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 4 is -CH 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. |
