Abstract
An apparatus and method for forming an alignment layer with uniform orientation is provided. An alignment layer-forming apparatus includes an ion source for generating ion beams and one or more masks disposed between the ion source and a substrate. The masks each have a reflective face directed to the substrate. The ion beams are reflected between the reflective face of each mask and a thin-film which is disposed on the substrate and which is processed into an alignment layer, whereby the alignment layer is formed with the ion beam finally applied to the thin-film. The orientation of a liquid crystal can be rendered uniform by varying the shape and/or arrangement of the reflective face of the mask. Hence, a liquid crystal display with no brightness or color non-uniformity can be manufactured.
