HIGH VELOCITY AND HIGH TEMPERATURE LIQUID CRYSTAL USING LIQUID CRYSTAL MIXTURE OF FLUORO ISOTHIONATE

摘要

PURPOSE: Provided is a nematic liquid crystal composition having high phase transition temperature of liquid crystals and high response velocity, which can be used for preparing LCD elements. CONSTITUTION: The nematic liquid crystal composition contains: 2-80wt% of a nematic liquid crystal compound represented by the formula 1 or nematic liquid crystal compounds represented by the formula 2 and 3, wherein the weight ratio of the compound represented by the formula 2 and the compound represented by the formula 3 is 1-80:1-80; 20-98wt% of at least one liquid crystal compound selected from the compounds represented by the formula 4, 5, and 6, wherein R2 and R3 are independently or simultaneously C1-C15 alkyl or alkoxy, B is phenyl or cyclohexyl, C is a single bond, -CH2CH2-, or -COO-, X and Y are independently or simultaneously hydrogen or fluoro atom, and Z is hydrogen, -OCF3, or fluoro atom.
