Patent ID: 7952658

Claim:
A polarizing film pair for use in a liquid crystal display (LCD) device, comprising: a first polarizing film including a first protective layer, a first polarization layer having a first absorption axis, a first retardation film having an optical axis normal to a surface of said first polarization layer, said first retardation film having a negative uniaxial birefringence having an in-plane retardation in a range of 0 to 15 nm and an orthogonal retardation of 50 to 123 nm, and a second retardation film having an optical axis parallel to said surface of said polarization layer and said first absorption axis, said second retardation film having a negative uniaxial birefringence having an in-plane retardation of 83 to 210 nm, said second retardation film having different refractive indexes (no) and (ne) along in-plane optical axes extending parallel to each other, and a refractive index (nz) along a direction normal to said surface of said polarization layer, said refractive indexes satisfying therebetween the relationship no=nz>ne, said first protective layer, said first polarization layer, said first retardation film and said second retardation film being consecutively layered; and a second polarizing film including a second protective layer, a second polarization layer having a second absorption axis, and a third retardation film having a birefringence having an in-plane retardation of 0 to 10 nm and an orthogonal retardation of 0 to 35 nm, said second protective layer, said second polarization layer and said third retardation layer being consecutively layered.
