  • Liquid crystalline compound for vertical alignment and a liquid crystalline composition comprising the same
    Publication number: 20050199857
    Abstract: A vertical alignment liquid crystalline compound containing a laterally substituted aromatic cyclic moiety. The liquid crystalline compound has a wide temperature range of the nematic phase, a high optical anisotropy and a high negative dielectric anisotropy. In addition, since the rotation viscosity and the K33/K11 ratio of the liquid crystalline compound are maintained at a low level, the liquid crystalline compound can be effectively used as a liquid crystalline medium having good image quality and a high response speed even when applied to thin liquid crystalline cells.
    Type: Application

  • Liquid crystalline compound having high optical anisotropy and liquid crystalline composition comprising the same
    Publication number: 20050133762
    Abstract: A novel liquid crystalline compound having a negative dielectric anisotropy and a high optical anisotropy. Since the rotation viscosity and the elasticity coefficient (K11/K33) of the liquid crystalline compound are maintained at a low level, the liquid crystalline compound can be effectively used as a liquid crystalline medium having good image quality and high response speed even when applied to thin liquid crystalline cells.
