Patent ID: 7643118

Claim:
A liquid crystal panel comprising at least a liquid crystal cell, a first polarizer disposed on one side of the liquid crystal cell, a second polarizer disposed on the other side of the liquid crystal cell and a retardation film (A) disposed between the liquid crystal cell and the first polarizer, wherein; the retardation film (A) contains a thermoplastic polymer having at least a substituent (a) represented by the following formula (I) and an in-plane retardation value (Re[750]) at a wavelength of 750 nm is larger than an in-plane retardation value (Re[550]) at a wavelength of 550 nm: wherein R 1 to R 7 each independently represent a hydrogen atom, a halogen atom, a straight-chain or branched alkyl group having 1 to 4 carbon atoms, a straight-chain or branched alkyl halide group having 1 to 4 carbon atoms, a straight-chain or branched alkoxy group having 1 to 4 carbon atoms, a straight-chain or branched thioalkoxy group having 1 to 4 carbon atoms, a straight-chain or branched alkoxycarbonyl group, an acyloxy group, an amino group, an azide group, a nitro group, a cyano group, a hydroxy group or a thiol group (provided that R 1 is not a hydrogen atom); wherein an absolute value of a photoelasticity coefficient of said retardation film (A) is 50×10 −12 (m 2 /N) or less.
