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.
揭示了一种乙烯砜衍生物,包括该乙烯砜衍生物的液晶组合物,以及使用相同液晶组合物的液晶显示装置的补偿膜。更具体地说,该乙烯砜衍生物是一种高质量视角补偿膜的液晶材料,与从正面测量的对比度相比,在倾斜角度测量时改善了对比度,并最小化了在黑色状态下根据视角的颜色变化。
