摘要:
Provided are a liquid crystal panel capable of constituting a liquid crystal display apparatus in which a contrast and a display color are unlikely to change depending upon a viewing angle and an azimuth, and a liquid crystal display apparatus using the liquid crystal panel. The liquid crystal panel of the present invention at least includes a liquid crystal cell, a first polarizer placed on one side of the liquid crystal cell, a second polarizer placed on another side of the liquid crystal cell, a first optical element placed between the liquid crystal cell and the first polarizer, a second optical element placed between the liquid crystal cell and the first optical element, and a third optical element placed between the liquid crystal cell and the second polarizer, in which an absorption axis of the first polarizer is perpendicular to an absorption axis of the second polarizer, the first optical element has a relationship of nz>nx=ny, the second optical element has a relationship of nx>ny=nz and a slow axis thereof parallel to an absorption axis of the first polarizer, and the third optical element has an optical isotropy.
