Title:
NEMATIC LIQUID CRYSTAL MIXTURE AND FLUORINATED CHLOROTERPHENYL
Document Type and Number:
Japanese Patent JP2003049167
Kind Code:
A
Abstract:
To provide non-cyano-type liquid crystal mixture free from the crystallization and the formation of smectic phase even at a low temperature, having a wide nematic temperature range, highly positive dielectric anisotropy and high birefringence and usable for an active matrix liquid crystal display having high performance.
The liquid crystal mixture contains at least one fluorinated chloroterphenyl of formula I: R-E-Cl (R is a ≤15C nonsubstituted or halogenated alkyl or alkenyl; one or more CH2 groups in the group R may be independently substituted with the group of formula 2 in a state free from directly bonded oxygen atoms; E is an enantiomer of formula 3 provided that at least one of the benzene rings is further fluorinated.).
