Patent

CA 1341098

The present invention is directed to a liquid crystal composition which comprises at least one liquid crystalline compound having an optically active .gamma.-lactone ring of the formula (A): Image wherein R1 is a group selected from the group consisting of Image n and a are each independently 0 or 1; R3 is an alkyl group having 1 to 15 carbon atoms; X and Y are each independently a group selected from the group consisting of a hydrogen atom, a halogen atom and a cyano group; R2 is a group of the formula: -(CO))m -R4; m is 0 or 1; R4 is a hydrogen atom or an alkyl having 1 to 15 carbon atoms; and the symbol * is an asymmetric carbon atom, and a chiral or non-chiral liquid crystal. The liquid crystal composition of the present invention is useful as an element for opto-electronic devices.
