  • Publication number: 20060103798
    Abstract: Disclosed is a vertically aligned liquid crystal display (VA-LCD) having wider viewing angle and having high contrast at the right angle and tilt angles. According to one embodiment of the present invention, the VA-LCD having liquid crystal cells in which liquid crystals with a negative dielectric anisotropy are filled and which is provided between a first polarizer and a second polarizer, whose absorption axises are perpendicular to each other, includes a sheet of +A plate and a sheet of ?C plate, disposed between the first polarizer and the liquid crystal cells; and a sheet of +A plate disposed between the second polarizer and the liquid crystal cells, wherein an optical axis of the +A plate near the first polarizer is perpendicular to the absorption axis of the first polarizer, and an optical axis of the +A plate near the second polarizer is perpendicular to the absorption axis of the second polarizer.

  • Publication number: 20050190326
    Abstract: Provided are a vertically aligned liquid crystal display (VA-LCD) with good viewing angle characteristics, which has liquid crystals with negative dielectric anisotropy (??<0). In the VA-LCD, a polynorbornene based polymer film is used as a protection film and/or as a negative C-plate retardation film for an upper polarization plate and/or a lower polarization plate. Therefore, high contrast characteristics for a front view and an oblique angle view are realized and color change for an oblique angle view can be minimized.
