Title:
ポリノルボルネン系重合体フィルムを用いる垂直配向液晶表示装置
Document Type and Number:
Japanese Patent JP4579161
Kind Code:
B2
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.
