  • In-plane switching liquid crystal display comprising compensation film for angular field of view using positive biaxial retardation film
    Patent number: 7671950
    Abstract: Disclosed is an in-plane switching liquid crystal display, which uses a positive biaxial retardation film while adjusting an optical axis direction and the retardation value of the positive biaxial retardation film. The in-plane switching liquid crystal display improves the contrast characteristic at a predetermined angular position as well as at a front position thereof, so a color shift according to the viewing angle in the black state is minimized.
    Type: Grant
    Filed: October 10, 2008
    Date of Patent: March 2, 2010
    Assignee: LG Chem. Ltd.
    Inventors: Byoung Kun Jeon, Serey Belyaev, Jeong Su Yu, Nikolay Malimonenko
