ABSTRACT:
A liquid crystal panel including a liquid crystal cell having an improved contrast ratio in an oblique direction and an improved color shift in an oblique direction is provided.A liquid crystal panel according to the present invention includes: a liquid crystal cell; a first polarizer arranged on one side of the liquid crystal cell; a second polarizer arranged on another side of the liquid crystal cell; a negative C plate and a negative A plate arranged between the liquid crystal cell and the first polarizer; and an isotropic optical element arranged between the liquid crystal cell and the second polarizer. The negative C plate is arranged between the first polarizer and the negative A plate.
