Zusammenfassung:	The present invention relates to a reactive liquid crystal compound. More specifically, the present invention relates to a liquid crystal compound capable of being optically arranged by having a molecular structure diphenyl sulfane rod shape structure of a compound, and to an optical compensation film including the same. According to the present invention, provided is a liquid crystal compound having a polymerizable terminal group in a terminal and having an ester group and an amide group as a connection ring as a diphenyl sulfane main chain, wherein wide viewing angle compensation and optical property improvement are possible, and a film can be easily formed. The liquid crystal compound is optically aligned and is photopolymerized. Accordingly, an optically aligned liquid crystal compound can be easily fixed. Also, an optical compensation film including the liquid crystal compound, a film patterned retarder (FPR) can be easily produced, and precise optical compensation is possible. 본 발명은 반응성 액정화합물에 관한 것으로서, 더욱 상세하게는 화합물의 분자구조상 디페닐설페인(diphenyl sulfane) 막대형상 구조를 가져 광학적 배열이 가능한 액정화합물 및 이를 포함하는 광학보상필름에 관한 것이다. 상기와 같은 본 발명에 따르면, 넓은 시야각 보상 및 광학특성의 개선이 가능하고 필름형성이 용이한 디페닐설페인 주쇄로 연결고리로 에스터 기 및 아마이드기를 갖고 말단에는 광중합이 가능한 말단기를 갖는 액정화합물을 제공함으로써, 액정화합물을 광학적으로 배향한 후 바로 광중합을 실시하여 광학적으로 배향된 액정화합물을 용이하게 고정시킬 수 있을 뿐만 아니라 상기 액정화합물을 포함하는 광학보상필름 및 FPR(film patterned retarder)의 제조가 용이하며 정밀한 광학적 보상이 가능한 효과가 있다.
