    摘要: PROBLEM TO BE SOLVED: To provide a method for producing a film in which uneven wind during the drying is suppressed, so that the film obtains good liquid crystal alignment and good other surface properties.SOLUTION: A method for producing a film comprises: a coating step in which a substrate is coated with a polymerizable liquid crystal composition that contains (A) a polymerizable liquid crystal compound, (B) an alignment control agent that is capable of controlling the alignment of the polymerizable liquid crystal compound, (C) a polymerization initiator and (D) a solvent; and a drying step in which the thus-formed coating film is dried. The alignment control agent is a compound represented by the following formula, and the alignment control agent is added in an amount of 0.005-0.2 pts.mass with respect to 100 pts.mass of the polymerizable liquid crystal compound.
