Abstract
A method that uses at least one hydrogen ion beam for alignment of liquid crystal molecules is proposed in the present invention. The method of the present invention is proposed to resolve the problems of physical destruction and surface deterioration of the alignment films caused by the conventional method using argon ions beams. The method of the present invention directly uses at least one hydrogen ion beam to impact the alignment film. Hence, the physical destruction of the alignment film is reduced. In addition, via the reaction between hydrogen ions and the alignment films, the quality of the alignment film is improved.
