DIFLUOROPHENYL LIQUID CRYSTAL COMPOSITION

摘要

The present invention provides a novel liquid crystal composition which exhibits a smectic C* phase and in which a fluorine-substituent-introduced liquid crystal compound that exhibits a smectic C* phase is used to enhance the reliability of a liquid crystal device driven by a TFT and to decrease the melting point thereof for expansion of the operation temperature of the liquid crystal device.;The liquid crystal composition of the present invention contains at least two liquid crystal compounds each containing a mesogenic group having at least three rings of which at least one is a 2,3-difluorobenzene-1,4-diyl group and two terminal groups having different structures, wherein a compound having a pyrimidine skeleton is not used.
