Patent ID: 8054425

Claim:
An alignment-treating method, including: a first ultraviolet ray irradiation step of conducting an alignment-treating for realizing an alignment of liquid crystals in a predetermined azimuth direction on a alignment layer of a substrate by obliquely irradiating the substrate with ultraviolet rays, and a second ultraviolet ray irradiation step of conducting an alignment-treating for realizing an alignment of liquid crystals in an azimuth direction different from the predetermined azimuth direction by obliquely irradiating a region of the substrate where ultraviolet ray irradiation has not been conducted in the first ultraviolet ray irradiation step with ultraviolet rays in an azimuth direction 180 degrees different from an azimuth direction of ultraviolet ray irradiation in the first ultraviolet ray irradiation step, in the first and second ultraviolet ray irradiation steps, the substrate being obliquely irradiated with ultraviolet rays, through a mask having stripe-shaped light shielding area and stripe-shaped opening, in an azimuth direction parallel to a longer direction of the stripe-shaped opening.
