ABSTRACT:
A novel liquid crystal display device is disclosed. The device comprises two polarizer films, a liquid crystal cell disposed between these two polarizer films wherein liquid-crystalline molecules are oriented substantially normal to the substrates under non-operative state in the absence of applied external electric field; at least one layer of a first optically-anisotropic layer having an optically positive refractive anisotropy having Re falling within a range from 40 to 150 nm at visible light; and at least one layer of a second optically-anisotropic layer having an optically negative refractive anisotropy, and having Re of 10 nm or less and Rth falling within a range from 60 to 250 nm at visible light.
