发明名称 LIQUID CRYSTAL PANEL AND LIQUID CRYSTAL DISPLAY APPARATUS
摘要 A liquid crystal panel according to an embodiment of the present invention 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 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. 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. A wavelength dispersion value (D1) of the biaxial optical element and a wavelength dispersion value (D2) of the negative C plate satisfy a relationship of D1>=D2.
