Patent ID: 7431972

Claim:
An optical film comprising an optically anisotropic layer ( 1 ) including a liquid crystalline compound, wherein the optically anisotropic layer ( 1 ) satisfies the following formulae (1) and (2): Re (450)/ Re (650)<1.25 Formula (1): wherein Re(450) and Re(650) are in-plane retardation values (unit: nm) of the optically anisotropic layer ( 1 ) at wavelengths of 450 nm and 650 nm, respectively; 0.09 <Re — m (550)/ d Formula (2): wherein Re_m(550) is an in-plane retardation value (unit: nm) of a uniaxial alignment layer in which the director of a liquid crystalline compound constituting the optically anisotropic layer ( 1 ) is aligned to be parallel in the plane at a wavelength of 550 nm, and d is the thickness of the uniaxial alignment layer (unit: nm).
