Patent ID: 7719644

Claim:
An optical compensation sheet comprising: a stretched polymer film: and an optical anisotropic layer containing a liquid crystal compound, wherein the optical compensation sheet has retardations satisfying relationships (A) to (F): 30 nm< Re (546)<150 nm (A) 100 nm< Rth (546)<400 nm (B) 0.5< Re (480)/ Re (546)<1 (C) 1.0< Re (628)/ Re (546)<2.0 (D) 1.0< Rth (480)/ Rth (546)<1.5 (E) 0.7< Rth (628)/ Rth (546)<1.0 (F) wherein Re (λ) is a retardation (nm) in a plane of the optical compensation sheet at a wavelength of λ nm; and Rth (λ) is a retardation (nm) in a direction perpendicular to the plane of the optical compensation sheet at a wavelength of λ nm.
