Abstract
Disclosed are a silicon 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 silicon 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.
