| 摘要 |
The invention provides a nematic liquid crystal composition useful in electrooptical display devices for its broad nematic temperature range, low electrical threshold and saturation voltages, steep electrooptical saturation curve and low viscosity. The admixture typically comprises: -Weight % -4-heptylphenyl-4'-butylcyclohexane carboxylate 20-40 -4-cyanophenyl-4'-propylcyclohexane carboxylate 8-20 -4-cyanophenyl-4'-butylcyclohexane carboxylate 8-20 -4-cyanophenyl-4'-pentylcyclohexane carboxylate 8-20 -5-butyl-2-cyanophenyl-1,3 dioxane 10-40 -4-cyanophenyl-4''-pentyl-4'-cyclohexyl benzoate 2-10 -4-cyanophenyl-4''-heptyl-4'-cyclohexyl benzoate 2-10 -chiral additive 0.1-0.8 -
