Abstract
Disclosed is an optical compensation film including a supporter, and an optical compensation layer disposed on at least one surface of the supporter and including a polymer of cholesteric liquid crystal molecules having a structure in which a plurality of parallel-arranged liquid crystal molecules are helically arranged, wherein the cholesteric liquid crystal layer has a helical axis that is bent and tilted to the supporter at an angle represented by the following Equation 1; a method of manufacturing the same; and a liquid crystal device (LCD) including the optical compensation film.
In Equation 1, H is a tilt angle of the helical axis of a layer of the cholesteric liquid crystal molecules; θB is a tilt angle of liquid crystal molecule contact with the supporter; θT is a tilt angle of a liquid crystal molecule disposed at a part of the layer furthest from the supporter; d is a thickness of the layer; d′ is a distance from the supporter along a vertical direction; γ is a degree of variation in tilt angle of helical axis; and γ≧0.01.
