摘要:
A ferroelectic smectic C liquid crystal mixture and a display element having a quick electrooptical response and a good memory property are provided, the ferroelectric mixture having a Ps of 60 nC/cm2 or more and a tilt angle of 24.degree. or more and comprising(A) a first component comprising at least one optically active compound expressed by the formula ##STR1## wherein l and m are 0 or 1, both are not 1; n is an integer of 3 to 8; X and Y are H, F, Cl, or CN, both X and Y are not H; A is --COO-- or --OCO--; and R is C3--8 alkyl or alkoxy , and(B) a second component comprising at least one optically active compound expressed by the formula ##STR2## wherein l, m, n and R are as defined above; and A is --COO--, --OCO--, --CH.sub.2 O-- or --OCH.sub.2 --, a total content of the first and second components being 60 mol % or more in the mixture.
