ABSTRACT:
A liquid crystal panel of the present invention comprises at least: a liquid crystal cell comprising a liquid crystal layer containing a liquid crystal molecule that is oriented in homogeneous alignment with no electric field applied thereto; a first polarizer placed on one side of the liquid crystal cell; a first optical element placed between the liquid crystal cell and the first polarizer; and a second polarizer placed on the other side of the liquid crystal cell, wherein the first optical element is substantially optically isotropic, the liquid crystal cell has an initial alignment direction that is substantially parallel to the direction of an absorption axis of the first polarizer, and the absorption axis of the first polarizer is substantially perpendicular to an absorption axis of the second polarizer. The liquid crystal panel shows less discoloration of images even when the screen is viewed from oblique directions.
