1. An method for forming a liquid crystal alignment layer in a thin-film on a substrate, comprising:
a step for preparing a substrate whereon a thin-film is formed that will be a liquid-crystal alignment layer;
a step for placing mask, having a reflective face on the substrate side, between the substrate and an ion source; and
a step for conveying the substrate, irradiating the thin-film on the substrate with an ion beam emitted from the ion source, and reflecting the ion beam between the thin-film and the reflective face of the mask, reflecting the ion beam in the orientation direction from the reflective face of the mask;
wherein:
the traveling direction of the substrate, in which the substrate is conveyed, is the same direction as the direction in which the ion beam is illuminated.
