The present invention relates to a liquid crystal composition, a polymer-dispersed liquid crystal composition containing same, and an advertisement system. The liquid crystal composition according to the present invention contains a specific proportion of a liquid crystal compound having a cyclohexyl structure, and thus, when applied to a polymer-dispersed liquid crystal and an advertisement system, a low birefringence is exhibited and, simultaneously, when voltage is not applied (off state), transmittance and side transmittance can be remarkably improved. La présente invention concerne une composition de cristaux liquides, une composition de cristaux liquides dispersés dans un polymère la contenant, et un système publicitaire. La composition de cristaux liquides selon la présente invention contient une proportion spécifique d'un composé de cristaux liquides ayant une structure cyclohexyle, et ainsi, lorsqu'elle est appliquée à un cristal liquide dispersé dans un polymère et à un système publicitaire, présente une faible biréfringence et, simultanément, lorsqu'une tension n'est pas appliquée (état éteint), permet d'améliorer remarquablement une transmittance et une transmittance latérale. 본 발명은 액정 조성물, 이를 포함하는 고분자 분산형 액정 조성물 및 광고 시스템에 관한 것으로, 본 발명에 따른 액정 조성물은 사이클로 헥실 구조를 갖는 액정 화합물을 특정 비율로 포함하여 이를 고분자 분산형 액정 조성물 및 광고 시스템에 적용시 낮은 복굴절률을 나타냄과 동시에 전압이 인가되지 않았을 때(off state) 투과율과 측면 투과율을 현저하게 향상시킬 수 있다.
