Abstract

The present invention not only arranges molecules of the photofunctional polymer liquid crystal alignment layer by controlling the intensity of polarized light beams from the outside, but also preferentially applies electric and electric fields to the electric field before irradiating light to the photo functional polymer liquid crystal alignment layer. By arranging the molecules of the optical functional polymer liquid crystal alignment film by irradiating the polarized light and then re-distributing the liquid crystal alignment film molecules by the polarized light rays can be produced a photo-functional polymer liquid crystal alignment film excellent in uniformity of the arrangement of the molecules.
