  • Patent number: 7656484
    Abstract: A method for forming an alignment layer for a liquid crystal display includes preparing a substrate, applying an alignment material for initial alignment of a liquid crystal, and applying a field flux (e.g., an electric or magnetic field) to the alignment material to determine the alignment direction of the alignment material. Further disclosed is an apparatus for forming an alignment layer for a liquid crystal display. The apparatus comprises a substrate stage on which a substrate is mounted, and an electric or magnetic field generator installed at the periphery of the substrate stage. According to the method and the apparatus, since the alignment direction of an alignment material is determined by using an electric or magnetic field, no physical contact with a substrate is required and thus the problem of light leakage caused by rubbing alignment is solved.
