<p>The present invention provides a ferroelectric liquid crystal composition having good orientation properties, and quick response property wherein the phase transition series of the composition assumes an order of isotropic liquid -> cholesteric phase -> chiral smectic C phase starting from the high temperature, and the SC* phase is exhibited in a wide temperature range including room temperature. Said composition comprises - a component A of a compound of formula: <CHEM> and/or a compound <CHEM> - a component B of a compound of the formula: <CHEM> - a component C of a compound of the formula: <CHEM> and - a component D of a compound of the formula: <CHEM> wherein R<1> and R<2> represent each an alkyl group having 1 to 18 carbon atoms; R<4>, R<5>, R<7> and R<8> represent each an alkyl group or alkoxy group having 1 to 18 carbon atoms, x represents -@O or -O@-, Y, and Z represent each a hydrogen atom, or a halogen atom, n is an integer of 0 to 10, and * indicates an asymmetric carbon atom.</p> |
