Zusammenfassung:	The present invention relates to a liquid crystal alignment layer and a method for manufacturing a vertically aligned liquid crystal display using the same. More particularly, the present invention relates to a liquid crystal alignment layer capable of homogeneously and vertically aligning liquid crystal molecules in a liquid crystal layer through hydrogen bonding, and a method for manufacturing the liquid crystal display using the same. The liquid crystal alignment layer and the liquid crystal display device according to the present invention can uniformly arrange the liquid crystal molecules without the conventional polyimide alignment layer by applying the aliphatic organic molecules including the hydrogen bonding unit capable of bonding with the substrate and can realize excellent electro-optic characteristics. In addition, a higher threshold voltage (Vth) can be realized, compared to a liquid crystal display device using the conventional polyimide alignment film, and an enhanced level of liquid crystal reaction speed which is 2-4 times faster than a rising time and a pulling time can be realized. 본 발명은 액정 배향층 및 이를 이용한 수직 배향 액정표시장치 제조방법에 관한 것으로, 더욱 상세하게는 수소 결합을 통해 액정층의 액정분자들을 균일하게 수직 배향할 수 있는 액정 배향층 및 이를 이용한 액정표시장치의 제조방법에 관한 것이다. 본 발명에 따른 액정 배향층 및 액정표시장치는 기판과 결합할 수 있는 수소 결합 단위를 포함하는 지방족 유기분자를 적용함으로써 기존의 폴리이미드 배향막없이 액정분자들을 균일하게 배열할 수 있고 우수한 전기광학특성을 구현할 수 있다. 또한, 기존 폴리이미드 배향막이 적용된 액정표시장치에 비해 더 높은 문턱 전압값(threshold voltage, Vth)을 구현할 수 있으며, 라이징 타임과 풀링 타임이 2~4배 정도 빨라지는 개선된 수준의 액정 반응속도를 구현할 수 있다.
