LIQUID-CRYSTAL-COMPATIBLE PARTICLE-CONTAINING LIQUID CRYSTAL, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a liquid-crystal-compatible particle-containing liquid crystal which contains a metal nanoparticle having excellent dispersion ability in a liquid crystal and which has an excellent response property in a lower temperature range when used to form a liquid crystal cell for a liquid crystal display device and to provide the liquid crystal display device using the same. SOLUTION: The liquid-crystal-compatible particle-containing liquid crystal contains a liquid-crystal-compatible particle composed of a metal nanoparticle made of nickel and a metal other than nickel and a liquid crystal molecule bound to the outer region of the metal nanoparticle. The metal nanoparticle may be a nickel-silver two-component nanoparticle. The liquid crystal display device 1 may have a liquid crystal cell 7 in which the liquid-crystal-compatible particle-containing liquid crystal L containing the liquid-crystal-compatible particle is filled. The liquid crystal cell 7 may contain the liquid-crystal-compatible particle-containing liquid crystal L and a chiral agent. The liquid-crystal-compatible particle-containing liquid crystal L may have a twist angle ranging from 180 to 270°in the liquid crystal cell 7. The liquid-crystal-compatible particle-containing liquid crystal L may contain the metal nanoparticle in an amount of 0.02 to 0.2 wt.% relative to the amount of the liquid crystal contained therein. The liquid crystal display device 1 may be a dot matrix panel utilizing a DUTY driving. COPYRIGHT: (C)2009,JPO&INPIT
