Liquid crystal panel, and liquid crystal display device

A liquid crystal panel, comprising a liquid crystal cell having a color filter having individual blue, green and red color regions, a first polarizer formed on one side of the liquid crystal cell, a second polarizer formed on the other side of the liquid crystal cell, and a compensation layer arranged between the first and second polarizers,

• wherein the compensation layer has an optical characteristic that the layer gives a larger in-plane retardation and a larger thickness direction retardation for a longer wavelength, and
• the liquid crystal cell has a liquid crystal layer in a vertical alignment mode, and the thickness direction retardation values Rth(B), Rth(G) and Rth(R) of the liquid crystal cell to light transmitted through the individual color regions in the liquid crystal cell satisfy the following relationship:
• |Rth(B)|<|Rth(G)|<|Rth(R)|
• wherein Rth(B) represents the thickness direction retardation value of the liquid crystal cell to light transmitted through the blue regions of the cell and having a wavelength of 450 nm, Rth(G) represents the thickness direction retardation value of the liquid crystal cell to light transmitted through the green regions of the cell and having a wavelength of 546 nm, and Rth(R) represents the thickness direction retardation value of the liquid crystal cell to light transmitted through the red regions of the cell and having a wavelength of 633 nm,
• provided that any thickness direction retardation value Rth is represented by the following expression:
• Rth=[{(nx1+ny1)/2}−nz1]×d1
• wherein nx1 represents the refractive index of the liquid crystal cell in the X axis direction in the plane of the cell (i.e., the direction along which the refractive index is maximum in the plane), ny1 represents the refractive index of the liquid crystal cell in the Y axis direction in the plane of the cell (i.e., the direction perpendicular to the X axis in the plane), nz1 represents the refractive index of the liquid crystal in the direction perpendicular to the X axis direction and the Y axis direction, and d1 represents the thickness [nm] of the liquid crystal cell.
