Abstract:
The liquid crystal panel of the present invention has a liquid crystal cell having a pair of transparent substrates provided with a color filter having each color region of blue, green and red, and a liquid crystal layer formed by injecting a liquid crystal material between the transparent substrates; an optical compensating layer provided over the liquid crystal cell; and a light source for irradiating light, in which the optical compensating layer cancels out retardation in the thickness direction for light of a wavelength (G), which passes through a green region of the liquid crystal cell, and retardation in the thickness direction for light of a wavelength (R), which passes through a red region of the liquid crystal cell. The liquid crystal panel of the present invention can realize higher contrast in viewing from an oblique direction.
