Abstract
A method for manufacturing liquid crystal alignment film of the present invention comprises the steps of: (1) aligning a transparent substrate film by rubbing; (2) laminating a surface protective sheet having a release force of 0.5 N/50 mm or less onto an aligned face of the transparent substrate; (3) coating a liquid crystal material comprising a liquid crystal monomer and/or a liquid crystal polymer onto the aligned face after releasing the surface protective sheet; and (4) fixing the liquid crystal material after aligning the liquid crystal material. The method can make satisfactorily align the liquid crystal material on the substrate.
