  • Publication number: 20190278140
    Abstract: The present invention provides a method for producing a substrate provided with an alignment film whose refractive index anisotropy is less likely to change and can be maintained at a high level even during long-term use. The method for producing a substrate provided with an alignment film includes: a film coating step in which an alignment film composition is applied to a surface of a substrate to form a film, the alignment film composition containing a first polymer that contains an azobenzene group in a main chain thereof; and a heating and exposure step in which the film is irradiated with light while the substrate is heated at 60° C. to 80° C. The light applied in the heating and exposure step is preferably within a wavelength range of 320 to 500 nm.
