Abstract:
1. A liquid crystal panel, at least 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 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, wherein: an absorption axis direction of the first polarizer is substantially perpendicular to an absorption axis direction of the second polarizer; the first optical element has a refractive index ellipsoid of nz>nx=ny; the second optical element has a refractive index ellipsoid of nx>ny=nz, and a slow axis direction thereof is substantially parallel to an absorption axis direction of the first polarizer; and the third optical element has isotropy substantially optically, where nx, ny, and nz represent a refractive index in a slow axis direction, a refractive index in a fast axis direction, and a refractive index in a thickness direction.
