PROBLEM TO BE SOLVED: To uniformly form a macromolecule liquid crystal film and to stably form a uniaxial optical film having high quality. SOLUTION: The surface of a substrate 1 is first subjected to an orientation treatment along a prescribed orientation direction by executing an orientation stage. Next, the surface of the substrate 1 is coated with a coating material 2 consisting of macromolecule liquid crystals 2a having a prescribed phase transition point and a prescribed b. p. at a prescribed thickness in a uniform state by executing a coating stage. In succession, a drying state is executed to dry the applied coating material 2 subjected to a low-temp. heat treatment at the b. p. or below to evaporate the solvent while maintaining the uniform state of the coating material. Finally, an aligning stage is executed. The uniaxial film 3 is formed by once subjecting the substrate 1 to the high-temp. heat treatment to the phase transition point or above, then slowly cooling the substrate down to the temp. below the phase transition point and aligning the macromolecule liquid crystals 2a included in the dried coating material 2 in the orientation direction. |
