METHOD FOR MANUFACTURING A PHASE RETARDATION FILM

摘要

The present invention relates to a method for manufacturing a phase retardation film, and more particularly, to a method for manufacturing a phase retardation film in which a polymer liquid crystal composition is oriented using electrical fields or magnetic fields, without forming an alignment layer, so as to manufacture the phase retardation film through a simple process. According to the method for manufacturing the phase retardation film of the present invention, since the polymer liquid crystal composition is oriented using the electrical fields or magnetic fields, a process of forming an alignment material layer is not used and a process of rubbing or optically aligning the alignment material layer may be eliminated, and thus the present invention exhibits the advantages of the manufacturing process being very quickly performed and a process line being more simply constructed to reduce manufacturing costs. Further, while conventionally the number of alignment processes is increased whenever a pattern is added, in the method for manufacturing a phase retardation film of the present invention, only the structure of the electrode need be differently set to form patterns having different shapes, and thus the present invention exhibits the advantage of an additional processes not being required.
