  • LIQUID CRYSTAL COMPOSITION AND LIQUID CRYSTAL DISPLAY DEVICE INCLUDING THE SAME
    Publication number: 20180208846
    Abstract: There are provided a liquid crystal composition containing one or two or more compounds represented by the general formula (I) and a liquid crystal display device including the liquid crystal composition. A liquid crystal composition containing a compound represented by the general formula (I) has high dielectric constant anisotropy and low viscosity and is of great practical use as a liquid crystal composition for liquid crystal displays. A liquid crystal display device including a liquid crystal composition according to the present invention has a high contrast, high-speed responsivity, high light resistance, and a lower occurrence of image sticking and display defects, and is effective for higher-speed response and high-quality reliability.

  • Polymerizable-compound-containing liquid crystal composition and liquid crystal display element using same
    Patent number: 10023801
    Abstract: There is provided a liquid crystal display device of a PSA type or the like that uses the polymerizable compound-containing liquid crystal composition, having a sufficiently fast response speed, capable of 3D displaying. Uniform and stable orientation control can be obtained at a lower energy cost. Provided are the polymerizable compound-containing liquid crystal composition containing one or two or more polymerizable compounds represented by general formula (M) as the first component, and containing one or two or more compounds represented by general formula (Na), general formula (Nb), or general formula (Nc) having a naphthalene unit as the second component. The liquid crystal display device uses the same.
