[EN] Disclosed are a vinylsulfone derivative, a liquid crystal composition comprising the same, and a compensation film for a liquid crystal display device using the same liquid crystal composition. More particularly, the vinylsulfone derivative is a liquid crystal material of a high-quality view angle compensation film, which improves a contrast ratio measured at a tilt angle when compared to a contrast ratio measured from the front surface and minimizes color variations in a black state depending on view angles. [FR] L'invention concerne un dérivé de vinylsulfone, une composition de cristaux liquides comprenant ledit dérivé et un film compensation destiné à un dispositif à cristaux liquides utilisant ladite composition. Le dérivé de vinylsulfone est, plus particulièrement, un matériau de cristaux liquides de film de compensation de qualité élevée à angle de visualisation qui améliore le rapport de contraste mesuré selon un angle d'inclinaison par rapport au rapport de contraste mesuré à partir d'une surface avant et minimise les variations de couleur d'un état noir en fonction des angles de visualisation.
