Abstract
A method of forming an orientation film of a liquid-crystal display device having two electrode plates and a liquid-crystal cell between the two electrode plates includes the steps of forming an organic film on a partial or overall surface of at least one plate of the two electrode plates and radiating accelerated ions containing neutral atoms to the partial or overall surface of the organic film coated on the plate. The organic film consists of liquid-crystal molecules. The radiation is done for etching the organic film and orienting the liquid-crystal molecules in a unidirectional manner. The angle of incidence of the accelerated ions is defined as 40.degree. to 80.degree. with respect to a normal line of the plate. It results in offering even orientation of liquid-crystal molecules included in the liquid-crystal display device.
