    • 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.
    • 本发明涉及一种用于制造相位延迟膜的方法,并且更具体地涉及一种用于制造相位延迟膜的方法,其中使用电场或磁场取向聚合物液晶组合物而不形成取向层,如此 以通过简单的工艺制造相位延迟膜。 根据本发明的相位延迟膜的制造方法,由于使用电场或磁场对聚合物液晶组合物进行取向,因此不使用形成取向材料层的工艺,并且不使用摩擦或光学取向 取向材料层可以被消除,并且因此本发明表现出制造过程的优点非常快速地被执行并且生产线被更简单地构造以降低制造成本。 此外,尽管每当添加图案时增加对准过程的数量,但是在本发明的用于制造相位延迟膜的方法中,仅需要不同地设置电极的结构以形成具有不同形状的图案,并且因此 本发明表现出不需要附加工艺的优点。
