| 简介 |
A novel optical compensation film is disclosed. The film comprises a transparent film having a ratio Re/Rth(450 nm) of Re and Rth at 450 nm of 0.4 to 0.95 times as large as Re/Rth(550 nm) at 550 nm, having Re/Rth(650 nm) at 650 nm of 1.05 to 1.93 times as large as Re/Rth(550 nm), and having Rth at 550 nm ranging from 70 nm to 400 nm, where “Re” is an in-plane retardation and “Rth” is a thickness-direction retardation; and an optically anisotropic layer having an in-plane optical anisotropy, formed of a composition comprising a liquid-crystalline compound, in which molecules of the liquid-crystalline compound are fixed in an alignment state, wherein the direction of orthogonal projection, onto a plane of the transparent film, of a mean orientation direction of molecular symmetry axes of the liquid-crystalline compound at the interface on the transparent film side is 45° with respect to the in-plane slow axis of the transparent film. |
