Patent ID: 7092058

Claim:
A method of manufacture of a liquid crystal display device, which includes an orientation film applied to a substrate surface which is brought into contact with a liquid crystal layer, and in which an orientation control performance and a pretilt angle are imparted to the orientation film, the method comprising the steps of: mounting a substrate to which the orientation film is applied on a stage which is sequentially transported to a main irradiation region and a sub irradiation region; generating two different kinds of polarized lights by performing polarization treatment of a light flux irradiated from one light source device; imparting an orientation control performance to the orientation film provided to the substrate which is transported to the main irradiation region by irradiating one of two different kinds of polarized lights to the orientation film; and transporting the substrate to the sub irradiation region and imparting a pretilt angle to the orientation film to which the orientation control performance is imparted by irradiating the other of the two different kinds of polarized lights to the orientation film.
