Abstract: A device for surface treating an alignment film used for forming a liquid crystal display comprising a glass substrate, an alignment film formed on a surface of the glass substrate, and a suspension in which the above alignment film is immersed, the suspension ball-type particles. In a first embodiment, a roller is adhered closely to the alignment film by the ball-type particles and is rotated in one direction by power applied from outside to form a plurality of gullies on the surface of the above alignment film. In other embodiments, a circular rotational body or a conical rotational body is adhered closely to the alignment film to provide a fixed shear rate between the suspension and the alignment film by rotational movement in one direction to form a plurality of circular gullies on the surface of the alignment film by the ball-type particles.
