发明名称 Optical film, polarizing plate, and liquid crystal display device
摘要 The present invention provides an optical film including at least two optically anisotropic layers, wherein one optically anisotropic layer satisfies Expression (1) described below, the other optically anisotropic layer satisfies Expression (2) described below, and a slow axis of the one optically anisotropic layer is parallel to a slow axis of the other optically anisotropic layer, 0≦̸Re(450)/Re(550)≦̸0.5  Expression (1) 0.95≦̸Re(450)/Re(550)≦̸1.05  Expression (2) where Re (λ) represents an in-plane retardation value (unit: nm) of the corresponding optically anisotropic layer measured at a wavelength of λ nm.
