LIQUID CRYSTAL PANEL AND LIQUID CRYSTAL DISPLAY

摘要

The liquid crystal panel includes a liquid crystal cell, a first polarizer on one side of the liquid crystal cell, a second polarizer on the other side of the liquid crystal cell, a first optically anisotropic element having a positive refractive index anisotropy disposed between the liquid crystal cell and the first polarizer, and a second optically anisotropic element having a negative refractive index anisotropy disposed between the first optically anisotropic element and the liquid crystal cell. Liquid crystal molecule in the liquid crystal cell is homogeneously aligned and have a pretilt angle of 0.5° or less in non-electric-field state. At least one of the first optically anisotropic element and the second optically anisotropic element has a ratio R450/R550 of 1.1 or more, where R550 is a retardation at a wavelength of 550 nm and R450 is a retardation at a wavelength of 450 nm.
