Abstract
Disclosed is an optical compensatory sheet which comprises a transparent support and an optically anisotropic layer provided thereon, wherein the optically anisotropic layer comprises a compound having a discotic structure unit in its molecule and has negative birefringence, and the discotic structure unit has a plane inclined from a plane of the transparent support at an angle varying along a direction of depth of the anisotropic layer. A liquid crystal display and a color liquid crystal display provided with the optical compensatory sheet are also disclosed.
