Fluorinated Liquid Crystalline Materials for AM-LCD Applications (Special Issue on Liquid-Crystal Displays)

概要

論文の詳細を見る
Flurorinated liquid crystal compounds having fluorophenyl, difluorophenyl and trifluorophenyl moieties combined with ester linkages, 1, 2-ethylenes and covalent bonds were prepared and checked for their physical properties i.e. mesophases, dielectric and optical anisotropy, viscosity, pretilt angle and threshold voltage. By introducing fluorine atom(s) into the molecules, optical anisotropy and threshold voltage decreased, though the nematic temperature range diminished. The investigated compounds were all chemically stable and by using the compounds nematic liquid crystalline mixtures having low threshold voltage, low viscosity, large optical anisotropy and wide nematic ranges which were suitable for AM-LCDs, could be obtained.
