An optically-compensatory sheet comprises an optically anisotropic layer that comprises a liquid crystal compound, wherein the liquid crystal compound in the optically anisotropic layer has Smax of 0.4 or more, in which Smax is a maximum value among S1, S2 and S3, S1 is an alignment order parameter in a vicinity of an interface between the optically anisotropic layer and air; S2 is an alignment order parameter in a vicinity of an interface on a side opposite to the interface between the optically anisotropic layer and air; and S3 is an alignment order parameter in an interior of the optically anisotropic layer.
