Abstract
An optical compensatory sheet comprises an optically anisotropic layer formed of discotic liquid crystal molecules provided on a transparent substrate. The liquid crystal molecules are horizontally aligned in the optically anisotropic layer. An average inclined angle between discotic planes of the discotic liquid crystal molecules and a surface of the transparent substrate is less than 5°. The discotic liquid crystal molecules are fixed in the optically anisotropic layer while keeping the horizontal alignment.
