Abstract
The present invention provides a method for producing a substrate with a photo-alignment film, which increases the refractive index anisotropy while reducing a decrease in production efficiency. The method for producing a substrate with a photo-alignment film includes the steps of: (A) forming on a surface of a substrate a film of a photo-alignment film material containing a polymer with a photo-functional group; (B) irradiating the film formed in the step (A) with polarized light obtained by polarizing light emitted from a light emitting diode lamp; and (C) irradiating the film having been subjected to the polarized light irradiation in the step (B) with polarized light obtained by polarizing light emitted from a metal halide lamp.
