Abstract

본 발명은 액정표시소자의 편광필름 부착장치에 관한 것이다.The present invention relates to a polarizing film attachment device of a liquid crystal display device.

종래에는 편광필름의 흡수축 사이의 각도의 정밀도가 보장받기 힘들며, 일측 편광필름의 부착후에는 흡수축 방향과 배향 방향 사이의 각도가 고정될 뿐만 아니라, 노덜 화이트 모드 액정표시소자의 제조시, 액정표시소자가 가장 밝게 보이도록 편광필름을 부착할 경우, 두 편광필름의 흡수축의 각도가 수직하지 않을 가능성이 매우 높으므로 큰트라스트가 저하되는 단점이 있었다. 본 발명은 두 편광필름 또는, 액정층과 두 편광필름을 투과한 빛의 투과도를 측정부와, 편광필름의 양 모서리부위를 고정함과 아울러, 액정 셀을 고정하는 고정부와, 상, 하부에는 편광필름 고정부 및 측정부가 각각 구비되어, 회전 및 상, 하 승강운동을 하는 운동부로 구성함으로써 편광필름 사이의 각도를 임의로 조정 할 수 있으며, 최대 또는 최소의 투과도를 전기적으로 확인하면서 편광필름의 부착을 가능하게 하고, 또한 편광필름 공급장치와 배경색 검사장치를 자동화시킬 경우, 편광필름의 부착 공정을 자동화 시키도록 한 것이다.Conventionally, the accuracy of the angle between the absorption axis of the polarizing film is difficult to be guaranteed, and after the attachment of one polarizing film, the angle between the absorption axis direction and the alignment direction is fixed, and in the manufacture of a nodal white mode liquid crystal display device, When the polarizing film is attached so that the display device looks the brightest, there is a high possibility that a large contrast is lowered because the angles of the absorption axes of the two polarizing films are very high. According to the present invention, the polarizing film or the liquid crystal layer and the transmittance of the light transmitted through the two polarizing films, the fixing portion for fixing the corners of the polarizing film, and fixing the liquid crystal cell, and the upper and lower The polarizing film fixing part and the measuring part are respectively provided, and the rotating part and the moving part which moves up and down can be adjusted arbitrarily, and the polarizing film can be arbitrarily adjusted, and the polarizing film is attached while checking the maximum or minimum transmittance electrically. It is possible to, and also to automate the polarizing film supply device and the background color inspection device, to automate the attachment process of the polarizing film.
