20160124131 | OPTICALLY ANISOTROPIC FILM AND METHOD FOR PRODUCING OPTICALLY ANISOTROPIC FILM - In a conventional optically anisotropic film, striped unevenness parallel to the carrying direction of a substrate (the direction in which the substrate flows when the optically anisotropic film is produced in a roll-to-roll manner) is sometimes generated. In addition, when a liquid crystal cured film is transferred to a body to be transferred, uniformity of the liquid crystal cured film after transfer is sometimes also not sufficiently satisfactory. An optically anisotropic film is now formed by laminating a substrate, an orientation film and a liquid crystal cured film in this order, the substrate satisfying the following formula (A): | 05-05-2016 |
