Title: METHOD FOR PRODUCING OPTICAL MEMBER
Abstract:
Provided is a method for producing an optical member having a first optical film and a second optical film formed on a substrate, either the first optical film or the second optical film being a phase contrast film and the remaining optical film being a polarizing film. The method comprises: a first optical film formation step in which a coating solution for a first optical film, the coating solution containing liquid crystal molecules and a solvent, is applied onto the substrate and dried, thereby forming the first optical film; an intermediate film formation step in which, after the first optical film formation step, a coating solution for an intermediate film which is different from the coating solution for the first optical film is applied on the first optical film and dried, thereby forming an intermediate film; and a second optical film formation step in which, after the intermediate film formation step, a coating solution for a second optical film, the coating solution containing liquid crystal molecules and a solvent, is applied onto the intermediate film and dried, thereby forming the second optical film.
