METHOD FOR MANUFACTURING PATTERN ALIGNMENT FILM, METHOD FOR MANUFACTURING PATTERN PHASE DIFFERENCE FILM USING THE SAME, AND MANUFACTURING DEVICE THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a pattern alignment film by which a large number of pattern phase difference films can be easily manufactured.SOLUTION: A method for manufacturing a pattern alignment film includes an exposure process for forming an alignment layer, which includes first exposure processing and second exposure processing for irradiating an alignment layer forming layer with polarized ultraviolet while continuously conveying a long alignment film forming film having a transparent film base material and the alignment layer forming layer formed on the transparent film base material and containing an optical alignment material. Polarization directions of polarized ultraviolet irradiation in the first exposure processing and the second exposure processing are different from each other, and the alignment layer forming layer is pattern irradiated with polarized ultraviolet by at least one of the first exposure processing and the second exposure processing.
