  • Polymerizable compound and liquid crystal composition including it
    Patent number: 8394468
    Abstract: Provided is a polymerizable compound with large solubility in a liquid crystal composition and high reactivity irradiated by ultraviolet in the longer wavelength range. Provided is a liquid crystal composition that satisfies at least one of characteristics such as high maximum temperature of a nematic phase, low minimum temperature of a nematic phase, small viscosity, suitable optical anisotropy, large negative dielectric anisotropy, large specific resistance, high stability to ultraviolet light and high stability to heat, or that is suitably balanced between at least two of the characteristics.
    Type: Grant
    Filed: May 7, 2010
    Date of Patent: March 12, 2013
    Assignees: JNC Corporation, JNC Petrochemical Corporation
    Inventors: Maiko Ito, Keiji Kimura, Norikatsu Hattori, Eriko Saegusa
