ABSTRACT:
It is possible to enhance the utilization efficiency of a light source and impart an orientation control performance and a pretilt angle to an orientation film in a short treatment time. Substrates to which orientation films are applied are mounted on stages which are sequentially transported to a main irradiation region and a sub-irradiation region. Light flux irradiated from a light source device having a single light source receives polarization treatment at a polarization unit, thus generating main polarized light and sub-polarized light. The main polarized light is irradiated to the orientation film formed on the substrate which is transported to a main irradiation region, thus imparting orientation control performance to the orientation film. Subsequently, the substrate is transported to a sub-irradiation region, and sub-polarized light is irradiated to the orientation film to which orientation control performance is already imparted, thus imparting a pretilt angle to the orientation film.
