Abstract

The present invention provides a method and a device for forming an alignment film of a liquid crystal display wherein the alignment film is patterned in a desired form on a substrate without using a separate mask. The present invention provides a method for forming an alignment film of a liquid crystal display, the method comprising steps of: coating an alignment film forming material on an entire surface of a substrate of the liquid crystal display; curing the alignment film forming material to form the alignment film; and forming a predetermined alignment film pattern using a means capable of selectively processing a portion of the alignment film without using a mask. In addition, the present invention provides an apparatus for forming an alignment film of a liquid crystal display, the apparatus comprising: a coating device for coating an alignment film forming material on an entire surface of a substrate of the liquid crystal display; and a means for forming a predetermined alignment film pattern by selectively processing a portion of the alignment film without using a mask.
