Optically anisotropic film, method of manufacturing the same, and liquid crystal display apparatus

摘要

An optically anisotropic film obtained from a mixture comprising a polymer and a liquid crystal compound, wherein retardation of the optically anisotropic film at 80 DEG C, 60 DEG C or 0 DEG C measured from a normal direction is 20-97%, 20-99% or 101-150%, respectively, of retardation at 30 DEG C, and an absolute value of a deviation in retardation by said liquid crystal compound is not greater than 6% when the optically anisotropic film is held at 30% for 200 hours, has the temperature dependence in accordance with the temperature dependence of retardation of a liquid crystal display cell, and a small variation of retardation by the liquid crystal compound with the lapse of time, and thus is suitable for use in a liquid crystal display apparatus.
