- 35 - HOE 89/F 096 Abstract of the Disclosure Ferroelectric liquid crystalline mixtures The novel ferroelectric liquid-crystalline mixtures are based on at least two mixture components of the general formula (I) Image (I) but additionally contain at least one optically active dope from one or more of the following groups a) optically active esters of tetrahydrofuran-2- carboxylic acid b) optically active aryl 2,3-epoxyalkyl esthers c) optically active 1,3-dioxolan-4-yl ethers. The ferroelectric LC mixtures have a high spontaneous polarization and facilitate substantial compensation of the pitch of the helix in a nematic phase.
