ABSTRACT:
An alignment-treating method including a first 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 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 irradiation step with ultraviolet rays in an azimuth direction 180° different from an azimuth direction of ultraviolet ray irradiation in the first irradiation step. In the first and second irradiation steps, the substrate is 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.
