摘要： 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.

摘要： There is provided: an optical film suitable for a liquid crystal display apparatus providing a colorless neutral display in all azimuth angle directions; a liquid crystal panel employing the optical film; and a liquid crystal display apparatus employing the liquid crystal panel. An optical film includes a transparent protective film, a polarizer, and a birefringent layer having a relationship of nx>ny=nz and positive uniaxial property, in the stated order, in which the polarizer and the birefringent layer are laminated directly through one of a pressure-sensitive adhesive and an adhesive.
