Ferroelectric liquid crystal composition.

摘要

The present invention provides a ferroelectric liquid crystal composition which can exhibit an SC* phase in an extensive temperature range inclusive of room temperature and which has quick response properties and a large tilt angle, and it also provides a switching element containing the above-mentioned ferroelectric liquid crystal composition and having excellent response properties. The present invention is connected with a ferroelectric liquid crystal composition comprising at least one component A and at least one component B described hereinafter, the content of said component A being from 30 to 95% by weight, the content of said component B being from 5 to 50% by weight, said component A being a compound represented by the formula (I) <CHEM> wherein R<1> is an alkyl group or alkoxy group having 1 to 18 carbon atoms, k is an integer of 1 or 2, and R<2> is a straight-chain or branched alkyl group, said component B being a ferroelectric liquid crystal compound having a spontaneous polarization of 10 nCcm<-><2> or more.
