Abstract:
1. A liquid crystal panel, comprising: 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 biaxial optical element placed between the liquid crystal cell and the first polarizer; and a negative C plate placed between the second polarizer and the biaxial optical element, wherein: a direction of an absorption axis of the first polarizer is substantially perpendicular to a direction of an absorption axis of the second polarizer; a refractive index ellipsoid of the biaxial optical element has a relationship of nx>nz>ny and a direction of a slow axis of the biaxial optical element is substantially parallel to the direction of the absorption axis of the first polarizer; a refractive index ellipsoid of the negative C plate has a relationship of nx=ny>nz; and a wavelength dispersion value (D said liquid crystal panel comprises only one biaxial optical element, said nz coefficient of said biaxial optical element is 0.3 to 0.6, and the liquid crystal cell includes a liquid crystal layer containing liquid crystal molecules aligned in a homeotropic alignment in the absence of an electric field.
