Abstract:
Disclosed is a novel liquid crystal compound, a liquid crystal composition comprising the same, and an optical film using the same liquid crystal composition. More particularly, there is provided a liquid crystal material of a viewing angle compensation film with high quality characteristics, which can improve a contrast ratio 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.
