摘要：
There is provided an optical film having a small size change with a temperature change of a support of a pattern retardation film.An optical film includes: a support comprising a polymer having a moisture permeability of 0.5% or more; a first retardation region and a second retardation region, in which birefringence thereof is mutually different; and an optically anisotropic layer in which the first retardation region and the second retardation region are alternately patterned for every one line.
