Abstract
Provided are a vertically aligned liquid crystal display (VA-LCD) with good viewing angle characteristics, which has liquid crystals with negative dielectric anisotropy (Δ∈<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.
