  • LIQUID CRYSTAL COMPOSITION
    Publication number: 20170096601
    Abstract: The present invention relates to a liquid crystal composition. The liquid crystal composition has low rotational viscosity, and simultaneously, has excellent low temperature stability, and thus, can be usefully used in IPS (In-Plane Switching) or FFS (Fringe-Field Switching) mode TV or monitors which require low voltage driving and high speed response properties, and liquid crystal display devices such as mobile notebooks or tablet PCs, which particularly requires low temperature stability.
