发明名称 ELLIPTIC POLARIZING PLATE AND VERTICALLY ALIGNED LIQUID CRYSTAL DISPLAY USING THE SAME
摘要 An elliptical polarizer with excellent viewing angle characteristics is provided which comprises at least a first polarizer, a first optical anisotropic layer, a second optical anisotropic layer, and a third optical anisotropic layer, laminated in this order, wherein the first optical anisotropic layer satisfies [1] 50‰¤Re1‰¤500, the second optical anisotropic layer satisfies [2] 0‰¤Re2‰¤20 and [3] -500‰¤Rth2‰¤-30, and the third optical anisotropic layer satisfies [4] 100‰¤Re3‰¤180 wherein Re and Rth indicate the retardation values in the plane and thickness direction, respectively, of each of the optical anisotropic layers.
