Abstract:
To provide an optical film, which may be used as a λ/4 plate and may provide a display device which has specific optical characteristics, may be manufactured with high productivity and has an excellent 3D-display performance. To provide a 3D-display device having a physical properties having excellent antireflective property and light fastness with high productivity. An optical film having at least one optically anisotropic layer, wherein an in-plane retardation. Re at an arbitrary wavelength in a visible light region is 80 nm to 201 nm, an Nz value represented by the following equation is 0.1 to 0.9, and when the in-plane retardations at wavelengths of 450 nm, 550 nm and 650 nm are referred to as Re450, Re550 and Re650, respectively, Re450/Re550 is 1.18 or less and Re650/Re550 is 0.93 or more. Nx=0.5+Rth/Re (Rth: a retardation in a thickness direction)
