본 발명은 비틀린 네마틱 모드(Twisted Nematic Mode : TN) LCD에 관한 것으로, 이색성 염료분자를 풀리머에 혼합하여 투명전극이 형성된 기판위에 도포하여 배향막을 형성함으로써, 종래의 배향막의 러빙공정시 발생되는 정전기와 이물질을 방지한다. 본 발명은 상하기판위의 투명전극 및 배향막을 형성하는 공정, 상기 배향막을 러빙하는 공정, 상기 상하 기판을 합착하는 공정, 상기 상하기판사이에 액정을 주입하는 공정으로 이루어지는 액정표시소자의 제조방법에 있어서, 상기 투명전극이 형성된 기판위에 이색성 염료와 풀리머를 혼합한 배향막을 도포하는 것을 특징으로 한다.The present invention relates to a twisted nematic mode (TN) LCD, wherein a dichroic dye molecule is mixed with a pulley and applied onto a substrate on which a transparent electrode is formed to form an alignment layer, thereby generating an alignment layer during a rubbing process of a conventional alignment layer. To prevent static electricity and foreign objects. The present invention relates to a method for manufacturing a liquid crystal display device comprising a step of forming a transparent electrode and an alignment film on an upper and lower substrate, a step of rubbing the alignment film, a step of bonding the upper and lower substrates, and a step of injecting liquid crystal between the upper and lower substrates. The method is characterized in that the alignment film is mixed with a dichroic dye and a primer on the substrate on which the transparent electrode is formed.
