ABSTRACT:
The present invention provides a liquid crystal display device comprising at least: a backlight; a polarizer; a first optically anisotropic layer with a retardation of 210 to 300 nm at a wavelength of 550 nm; a second optically anisotropic layer with a retardation of 50 to 140 nm at a wavelength of 550 nm; a third optically anisotropic layer with negative optical anisotropy; a liquid crystal cell comprising upper and lower substrates facing each other and a liquid crystal layer sandwiched between the upper and lower substrates; a fourth optically anisotropic layer with a retardation of 50 to 140 nm at a wavelength of 550 nm; a first optically anisotropic layer with a retardation of 210 to 300 nm at a wavelength of 550 nm; and a polarizer, arranged in piles in this order from the backlight, the second optically anisotropic layer comprising at least a liquid crystal film with a fixed nematic hybrid liquid crystal orientation structure. The liquid crystal display device provides bright images and is high in contrast and less in viewing angle dependency.
