  • In-plane switching liquid crystal display including viewing angle compensation film using +A-plate
    Publication number: 20050248707
    Abstract: Disclosed is an in-plane switching liquid crystal display. The in-plane switching liquid crystal display uses at least one A-plate and adjusts the optical axis direction and the retardation value of the A-plate, thereby improving the contrast characteristic at a front and at a predetermined inclination angle of the in-plane switching liquid crystal display while minimizing a color shift according to viewing angles in the black state.

  • In-plane switching liquid crystal display comprising compensation film for angular field of view using negative biaxial retardation film and (+) C- plate
    Publication number: 20050200792
    Abstract: The present invention relates to an in-plane switching liquid crystal display comprising a negative biaxial retardation film and a positive C-plate, as viewing-angle compensation films. By the use of such viewing-angle compensation films, the contrast characteristics at the front side and inclination angle of the in-plane switching liquid crystal display can be improved and color shift with viewing angle in the dark state can be minimized.

  • In-plane switching liquid crystal display comprising compensation film for angular field of view using positive biaxial retardation film
    Publication number: 20050110933
    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.

  • Complex light-compensation C plate with two or more of C plates different in dispersion ratio value and liquid crystal display using the same
    Publication number: 20050057714
    Abstract: Disclosed is a complex light compensation C plate including at least two C plates representing different dispersion ratio values, respectively. The complex light compensation C plate improves a contrast characteristic of a liquid crystal display device at various viewing angles and has a broadband wavelength dispersion characteristic capable of minimizing color variation depending on various viewing angles in a black state of an LCD.
