    • A liquid crystal display device having at least two optically anisotropic body sheets (A, B) and a liquid crystal cell between a pair of polarizers disposed in a positional relationship that their absorption axes are generally perpendicular to each other. When the refractive indices along the slow axes in the plane of the sheets (A, B) measured by a light of a wavelength of 550 nm are denoted by nxA and nxB, the refractive indices in the direction perpendicular to the slow axes in the plane are denoted by n yA and nyB, and the refractive indices in the direction of the thickness are denoted by nzA and nzB, nzA > nyA and nzB> nyB. The sheets (A, B) are in a positional relationship that the slow axes in the plane of the sheets (A, B) are generally parallel or perpendicular to each other. The sheet (A) and the polarizer disposed near the sheet (A) are in a positional relationship that the slow axis in the plane of the sheet (A) is generally parallel or perpendicular to each other. The antireflectivity, scratchability, and durability are excellent, the angle of view is wide, and uniform display when viewed even from any direction and a high contrast are achieved.
    • 具有至少两个光学各向异性体片(A,B)和一对偏振片之间的液晶单元的液晶显示装置,其位置关系使吸收轴彼此垂直。 当通过波长为550nm的光测量的片材(A,B)的平面中的慢轴的折射率由nxA和nxB表示时,在与平面中的慢轴垂直的方向上的折射率 由n yA和nyB表示,并且厚度方向上的折射率由nzA和nzB,nzA> nyA和nzB> nyB表示。 片材(A,B)处于片材(A,B)的平面中的慢轴大致平行或垂直的位置关系。 位于片材(A)附近的片材(A)和偏振片处于与片材(A)的平面中的慢轴大致平行或垂直的位置关系。 抗反射性,耐擦伤性和耐久性优异,视角宽,并且即使从任何方向观察均匀的显示和高对比度。
