Patent ID: 7397524

Claim:
A vertically aligned LCD (VA-LCD) in a multi-domain mode or using a chiral additive, provided with a positive compensation film, in which a vertically aligned panel (VA-panel) is obtained by injecting liquid crystal having a negative dielectric anisotropy (Δ∈<0) or a positive dielectric anisotropy (Δ∈>0) into a gap between upper and lower glass substrates, upper and lower polarizing plates are arranged above the upper and lower surfaces of the VA-panel so that optical absorption axes of the polarizing plates are perpendicular to each other, and a cell gap in the range of 3 μm to 8 μm is maintained, comprising: the positive compensation film including one or more of a first retardation film (+A-plate) satisfying the condition of n x >n y =n z , and including a second retardation film (−C-plate) satisfying the condition of n x =n y >n z , for forming a liquid crystal cell, wherein said n x and n y represent in-plane refractive indexes between the VA-panel and the upper and lower polarizing plates, and said n z represents a thickness refractive index, wherein said first retardation film is arranged such that an optical axis of said first retardation film is perpendicular to an optical absorption axis of the neighboring polarizing plate, and a total thickness retardation (R −C +R VA ) including the thickness retardation of said second retardation film and the thickness retardation of the VA-panel has a positive value.
