ABSTRACT:
A process for the producing a coating fluid of the present invention comprises a step of adjusting a pH of the coating fluid by mixing ammonium hydroxide into an acid solution containing a lyotropic liquid crystal compound and a solvent. Further, a process for the producing an optically anisotropic film of the present invention comprises a step of obtaining an optically anisotropic film by casting the coating fluid produced by the aforementioned process for production of the coating fluid in a thin film state, followed by drying.
