  • Patent number: 7459189
    Abstract: A liquid crystal/polymer composite is sandwiched between a pair of substrates with electrodes, the polymer forms a plurality of column resins, column resins of which the major axis directions substantially agree with the normal direction of the substrate plane and column resins which are aligned on the tilt coexist, the content of the polymer is at least 10 wt %, the alignment of the liquid crystal substantially agrees with the normal direction and the liquid crystal is in a light transmitting state under application of no voltage, and the alignment of the liquid crystal changes and the liquid crystal is in a light scattering state under application of a voltage.

  • Publication number: 20080123038
    Abstract: Provided is a liquid crystal display enabling well-balanced improvement of contrast and the response speed against voltage application, in vertical alignment mode using a vertical alignment type liquid crystal. A liquid crystal display includes a couple of substrates disposed facing each other, and a liquid crystal layer disposed between the pair of substrates, the liquid crystal layer containing liquid crystal molecules having a negative dielectric anisotropy, each pixel in the liquid crystal layer having more than two regions, the liquid crystal molecules in one of the regions having a pre-tilt angle different from that of the liquid crystal in another region.
