| titleOfInvention | Method for manufacturing polarization diffraction element, and polarization diffraction element or hologram element obtained by this manufacturing method |
| abstract | An object of the present invention is to provide a polarization diffraction grating or a polarization hologram element having at least two regions having different polarization diffractivities by a simple manufacturing method. Irradiation portions and non-irradiation are formed by irradiating a coating film of a birefringence inducing material with polarizing ultraviolet light using a method such as a lattice mask and two-beam interference. Subsequently, when a mask having a desired pattern is used to irradiate ultraviolet light having different electric field vibration directions and the film is heated and cooled to induce orientation of the irradiated portion, the maximum refraction of the birefringence inducing portion is observed when viewed from the front. Two grating-like regions having different rate directions can be formed in the same film, and a polarization diffraction grating or a polarization hologram element having at least two regions having different polarization diffraction capabilities can be provided.
