ABSTRACT:
Disclosed are a novel liquid crystal compound containing a sulfone group, a liquid crystal composition comprising the same, and an optical film using the same liquid crystal composition. More particularly, there are provided a liquid crystal material for a viewing angle compensation film with high quality characteristics, which can improve a contrast ratio measured at a tilt angle to the front and minimize variations in color with viewing angles in a black state, a liquid crystal composition comprising the same liquid crystal material, and a compensation film obtained from the same liquid crystal composition.
