Disclosed is an optical compensatory sheet comprising a transparent support and an optically anisotropic layer provided thereon and having an optic axis inclined at 20 to 34 degrees from the normal of the sheet, wherein the optically anisotropic layer is formed from a discotic compound capable of forming a discotic nematic phase and an organic compound which has compatibility with the discotic compound and is capable of lowering a transition temperature of the discotic nematic phase by at least 10°C. Further, a liquid crystal display provided with the optical compensatory sheet is disclosed.
