Abstract:
A liquid crystal display device comprising:a first polarizing plate having a transmitting axis in a specified direction; an optically biaxial anisotropic sheet; a liquid crystal layer formed of vertically oriented nematic liquid crystal molecules possessing a negative dielectric anisotropy; and a second polarizing plate having a transmitting axis perpendicular to said specified direction, in this order; an optically uniaxial anisotropic sheet selectively being provided either between said liquid crystal layer and said optically biaxial anisotropic sheet or between said liquid crystal layer and said second polarizing plate; and, â€ƒwherein: retardation of said optically uniaxial anisotropic sheet and retardation of said liquid crystal layer have opposite polarity and an absolute value of the retardation of said optically anisotropic uniaxial sheet ranges from 75 to 100% of that of said liquid crystal layer.
