<p>The present invention provides an elliptical polarizer with excellent viewing angle characteristics. The elliptical polarizer comprises at least a first polarizer, a first optically anisotropic layer, a second optically anisotropic layer, and a third optically anisotropic layer, laminated in this order, the first optically anisotropic layer satisfying [1] 50‰¤Re1‰¤500, [2] 30‰¤Rth1‰¤750, and [3] 0.6‰¤Rth1/Re1‰¤1.5, the second optically anisotropic layer satisfying [4] 0‰¤Re2‰¤20 and [5] -500‰¤Rth2‰¤-30, and the third optically anisotropic layer satisfying [6] 100‰¤Re3‰¤180, [7] 50‰¤Rth3‰¤600, and [8] 0.5‰¤Rth3/Re3‰¤3.5, wherein Re indicates the retardation value in the plane of each optically anisotropic layer and Rth indicates the retardation value in the thickness direction of each optically anisotropic layer.</p> |
