Abstract:
1. A system for producing an optical orientation film, comprising: a means of continuously feeding an irradiation target substrate comprising a first continuous transparent resin substrate and an orientation layer on one surface of the first continuous transparent resin substrate; a means of continuously feeding a continuous photomask comprising a second continuous transparent resin substrate and a desired ultraviolet shielding pattern on one surface of the second continuous transparent resin substrate; a means of producing a laminate by laminating the continuously-fed photomask on the orientation layer of the continuously-fed irradiation target substrate; a means of exposing the orientation layer in the pattern by irradiating the orientation layer of the laminate from the photomask side with first linearly polarized light in a constant polarization direction; and a means of removing the photomask from the laminate irradiated with the linearly polarized light.
