Abstract:
The present invention provides a transparent liquid crystal display device which is less in display characteristics and viewing angle dependency and can provide bright images and high contrasts. The transparent liquid crystal display device comprises at least: a backlight; a polarizer; a second optical anisotropic layer with a retardation of 50 to 180 nm at a wavelength of 550 nm; a first optical anisotropic layer with a retardation of 20 to 140 nm at a wavelength of 550 nm; a homogeneously aligned 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 optical anisotropic layer with a retardation of 50 to 200 nm at a wavelength of 550 nm; and a polarizer, arranged in piles in this order from the backlight, wherein the first optical anisotropic layer comprising at least a liquid crystal film with a fixed nematic hybrid liquid crystal alignment structure.
