Abstract:
The present invention relates to a radial-shaped liquid crystal compound, and an optical film and a liquid crystal display device comprising the same. Particularly the present invention provides a compound represented by Chemical Formula 1 comprising a radial-shaped core of tetraphenyl ethylene in which four phenyl groups are bonded to an ethylene group, and makes it possible to provide an optical film which can minimize the change of color according to viewing angle and has an improved contrast ratio and high refractive anisotropy, and a liquid crystal display device comprising the same, by using the compound.
