description PROBLEM TO BE SOLVED: To provide a method for producing an optical film including a method of aligning a liquid crystallin compound at a high alignment level even in working in a roll-shaped film, and to provide a production device for the production method, namely, to provide a method for producing an optical film having an excellent viewing angle and a production device. SOLUTION: The method for producing an optical film having an optically anisotropic layer obtained by curing a liquid crystallin compound on a support sequentially includes: a step where the surface of the support or the surface of an intermediate layer is coated with a liquid crystallin compound; a first magnetic field applying step performed onto the coated liquid crystallin compound layer; a first step where the liquid crystallin compound is cured by active rays; a second magnetic field applying step; and a second step where the liquid crystallin compound is cured by active rays.
