Abstract:
A transmissive liquid crystal display device comprises at least a backlight, a polarizer, a first optically anisotropic layer with a retardation of 50 to 140 nm at a wavelength of 550 nm, a second optically anisotropic layer with negative retardation, a homogeneously oriented liquid crystal cell comprising upper and lower substrates facing each other and a liquid crystal layer sandwiched between the upper and lower substrates, a third optically anisotropic layer with a retardation of 130 to 210 nm at a wavelength of 550 nm; and a polarizer, arranged in piles in this order from the backlight, the first optically anisotropic layer comprising at least a liquid crystal film with a fixed nematic hybrid liquid crystal orientation structure, and is less in display characteristic variation, bright in display, high in contrast, and less in viewing angle dependence.
