  • ECB-LCD having an excellent viewing angle and color characteristics
    Patent number: 8934074
    Abstract: There is provided an electrically controllable birefringence liquid crystal display (ECB-LCD) device, including: a liquid crystal panel including a first substrate, a second substrate, and a liquid crystal cell interposed between the first substrate and the second substrate and including a liquid crystal having positive dielectric anisotropy, the liquid crystal cell having a cell gap of 1 to 5 ?m and operating in an ECB mode; a first polarizer disposed on an upper portion of the first substrate and having a first absorption axis; a second polarizer disposed on a lower portion of the second substrate and having a second absorption axis; a first liquid crystal film interposed between the first substrate and the first polarizer; and a second liquid crystal film interposed between the second substrate and the second polarizer; wherein the first liquid crystal film includes a first base substrate; and a first liquid crystal layer formed on a surface of the first base substrate and including a nematic liquid crysta

  • Optical film, preparation method of the same, and liquid crystal display comprising the same
    Patent number: 8089585
    Abstract: The present invention relates to an optical film, a method for manufacturing the same, and a liquid crystal display device including the same. In detail, the optical film according to the present invention includes an acryl-based substrate, a liquid crystal alignment film, and a liquid crystal film, the liquid crystal alignment film can maintain strong adhesion strength between the acryl-based substrate and the liquid crystal alignment film and between the liquid crystal alignment film and the liquid crystal film by further introducing a monomer having a functional group capable of performing crosslinking reaction to the photoreactive polymer.
