Document Type and Number:
Japanese Patent JP2646314
Kind Code:
B2
Abstract:
An optically active 4-mercaptocinnamic acid derivative represented by general formula (1) koxy group alkylthio group having 6 to 14 carbon atoms; X is H or F; Y is H or CH3; n is 0 or 1; Z is CH3 or CF3; and R2 represents a C2-8 alkyl group, preparation method, bistable or tristable liquid crystal composition containing at least one such derivative, and a liquid crystal display device including such a liquid crystal composition. The compound of general formula (1) decreases liquid crystal temperature range and broadens it, and enables realizing a bistable or tristable chiral smectic phase. The compound can be used alone or as blended with other liquid crystals having a smectic phase or ferroelectric liquid crystals as a material for liquid crystal devices.
