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 S
max
of 0.4 or more, in which S
max
is a maximum value among S
1
, S
2
and S
3
, S
1
is an alignment order parameter in a vicinity of an interface between the optically anisotropic layer and air; S
2
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 S
3
is an alignment order parameter in an interior of the optically anisotropic layer.
