Claim:
A liquid crystal panel, comprising: a liquid crystal cell, a first polarizer arranged on one surface of the liquid crystal cell; a second polarizer arranged on an other surface of the liquid crystal cell; a first optical compensation layer arranged between the first polarizer and the liquid crystal cell; and a second optical compensation layer arranged between the second polarizer and the liquid crystal cell, wherein: the first optical compensation layer satisfies the following mathematical formulae (1) and (2), and the second optical compensation layer satisfies the following mathematical formulae (3) and (4), nx>ny≧nz (1) ( Re[ 450 ]/Re[ 550])<1.00 (2) nx≧ny>nz (3) ( Rth[ 450 ]/Rth[ 550])≧1.10 (4) where in the mathematical formulae (1), (2), (3), and (4), nx denotes a maximum refractive index in a plane direction of each of the first optical compensation layer and the second optical compensation layer, ny denotes a refractive index in a direction that is orthogonal to the nx direction in the plane direction of each of the first optical compensation layer and the second optical compensation layer, and nz denotes a refractive index in the thickness direction of each of the first optical compensation layer and the second optical compensation layer, which is orthogonal to each of the nx and ny directions, Re[450] denotes an in-plane retardation Re (nm) of the first optical compensation layer at a light wavelength of 450 nm, Re[550] denotes an in-plane retardation Re (nm) of the first optical compensation layer at a light wavelength of 550 nm, each of Re[450] and Re[550] is expressed by the following mathematical formula (5), Rth[450] denotes a retardation Rth (nm) in a thickness direction of the second optical compensation layer at a light wavelength of 450 nm, Rth[550] denotes a retardation Rth (nm) in the thickness direction of the second optical compensation layer at a wavelength of 550 nm, and each of Rth[450] and Rth[550] is expressed by the following mathematical formula (6), Re =( nx−ny )× d (5) Rth =( nx−nz )× d (6) where in the mathematical formulae (5) and (6), d denotes each of thicknesses (nm) of the first optical compensation layer and the second optical compensation layer, and nx, ny, and nz denote the same as those in the mathematical formulae (1), (2), (3), and (4).
