An object of the present invention is to provide a method for producing an optical compensation film capable of efficiently producing a high-quality optical compensation film having uniform orientation of constituent molecules. A coating step of the solution containing the polymerizable liquid crystal compound is applied onto a supporting substrate, a heating step of heating to a temperature T H of the coating film obtained in the coating step to evaporate the solvent, the heating step cooling step to cool to room temperature T R of the coating film formed through the, and light is irradiated to the coating film through said cooling step, precision in the manufacturing method of an optical compensation film comprising a polymerized to the polymerization process, the temperature control, in particular cooling process By controlling to, an optical compensation film having a uniform orientation of constituent molecules and a good quality can be efficiently produced. It can also be applied to the production of an optical compensation film having excellent wavelength dispersion control characteristics. [Selection] Figure 1 |
