摘要： A ferroelectric chiral smectic liquid crystal mixture comprising at least one compound of the formula (I): wherein R11 and R12 represent, independently each other, a C1-C20 alkyl, alkoxy or alkoxyalkyl group which may be substituted by at least one halogen atom and may have an unsaturated bond; A11, A12 and A13 represent, independently each other, a phenylene group which may be substituted by a fluorine atom, or the like; * indicates an asymmetric carbon atom; Z is a hydrogen atom or a fluorine atom; n is an integer of 0 to 10; r, s, t and u are each 0 or 1, provided that when u is 1, the compound (I) is a trans-olefin, and at least one compound of the formula (II): wherein R21 is a saturated or unsaturated C3-C20 alkyl group or a saturated or unsaturated C3-C20 alkoxyalkyl group; A21, A22 and A23 represent, independently each other, a phenylene group which may be substituted by a fluorine atom or the like; X2 is —C≡C— or the like; Z is a hydrogen atom or a fluorine atom; n is an integer of 1 to 10; m is 0 or 1; and * indicates an asymmetric carbon atom, which liquid crystal mixture has a high response speed and a small dependency of &tgr;-Vmin characteristic on temperature and a wide temperature driving margin.
