Abstract

이 발명은 저전압 구동 액정표시소자를 위한 배향막에 관한 것으로서, 더욱 상세하게 말하자면, 배향특성이 다른 이중 배향막을 이용하여 액정의 구동전압을 낮추도록 하는 저전압 구동 액정표시소자를 위한 배향막에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alignment film for a low voltage driving liquid crystal display device, and more particularly, to an alignment film for a low voltage driving liquid crystal display device for lowering the driving voltage of a liquid crystal using a dual alignment film having different alignment characteristics.

이 발명의 실시예에서, 수직 배열 구조를 갖는 HOMEOTROPIC 배향을 이용하여 액정과 배향막의 계면에서 틸트 앵글을 증가시키고 전계에 의한 액정의 반응을 민감하게 되도록 하여 액정의 구동 전압을 낮춤으로써 액정 표시 장치 패널의 전체적인 소비 전력을 줄일 수 있는 효과를 가진 저전압 구동 액정표시소자를 위한 배향막을 제공할 수 있다.In the embodiment of the present invention, a liquid crystal display panel is used by increasing the tilt angle at the interface between the liquid crystal and the alignment layer by using a homeotropic alignment with a vertically arranged structure and making the reaction of the liquid crystal by the electric field sensitive to lower the driving voltage of the liquid crystal. It is possible to provide an alignment film for a low voltage driving liquid crystal display device having an effect of reducing the overall power consumption.
