Abstract:
1. A liquid crystal panel, comprising a liquid crystal cell, a first polarizer disposed on one surface side of the liquid crystal cell, a second polarizer disposed on the other surface side of the liquid crystal cell, and first and second optical compensation layers disposed between the first and second polarizers, wherein the liquid crystal cell satisfies a relationship of 0.8<Re[450]/Re[550]<1, the first optical compensation layer satisfies relationships of an Nz coefficient is from 0.8 to 1.4 and 0.8 <Re[450]/Re[550]<1, and the second optical compensation layer satisfies relationships of nx=ny>nz and 0.98<Re[450]/Re[550]<1.04, the Nz coefficient is calculated from an expression of the Nz coefficient =(nx−nz)/(nx−ny), and the Re[λ] is calculated from an expression of the Re[λ]=(nx−ny)×d, and the nx represents the refractive index in the in-plane X axis direction (the axis direction along which the refractive index in the plane is the largest), the ny represents the refractive index in the in-plane Y axis direction (the in-plane direction orthogonal to the X axis direction), the nz represents the refractive index in the direction orthogonal to the X axis and Y axis directions, the d represents a thickness (nm), and the λ represents a wavelength.
