Zusammenfassung:	The present application relates to a reactive light stabilizer compound, a liquid crystal composition comprising the same, and a liquid crystal display device comprising the same. The reactive light stabilizer compound according to an embodiment of the present invention can achieve low-temperature stability and an afterimage alleviating effect at the same time without adversely affecting various properties of a liquid crystal composition such as a transparent point, modulus of elasticity, dielectric anisotropy or refractive index anisotropy and the like of a liquid crystal composition, and in a mode that requires an exposure process, the voltage retention rate (VHR) is increased and the RDC is decreased to alleviate afterimages. 본원은 반응성 광 안정제 화합물, 이를 포함하는 액정 조성물, 및 이를 포함하는 액정 표시 장치에 관한 것이다. 본 발명의 일 구현예에 따른 반응성 광 안정제 화합물은 액정 조성물의 투명점, 탄성계수, 유전율 이방성 또는 굴절률 이방성 등 액정 조성물의 제반 물성에 불리한 영향을 미치지 않으면서도 저온 안정성과 잔상 개선 효과를 동시에 달성할 수 있으며, 노광공정이 필요한 모드에서 전압유지율(VHR)은 높이고 RDC는 낮추어 잔상을 개선할 수 있다.
