A novel optical compensatory sheet is disclosed. The sheet comprises an optically anisotropic layer thereon comprising at least one compound represented by Formula (I) (R<SUP>1</SUP>-X<SUP>1</SUP>-)<SUB>m</SUB>Ar<SUP>1</SUP>(-COOH)<SUB>p</SUB>, Formula (II): (R<SUP>2</SUP>-X<SUP>2</SUP>-)<SUB>n</SUB>Ar<SUP>2</SUP>(-SO<SUB>3</SUB>H)<SUB>q </SUB>or Formula (III): (R-)<SUB>s</SUB>Ar(-Y)<SUB>r</SUB>; where Ar<SUP>1 </SUP>denotes an aromatic heterocyclic group or aromatic condensed carbocyclic group, X<SUP>1 </SUP>denotes a single bond or divalent linking group, R<SUP>1 </SUP>denotes an alkyl group, and m and p are integers from 1 to 4; where Ar<SUP>2 </SUP>denotes an aromatic heterocyclic group or aromatic carbocyclic group, X<SUP>2 </SUP>denotes a single bond or divalent linking group, R<SUP>2 </SUP>denotes an alkyl group, n is an integer from 1 to 4 and q is an integer from 1 to 4; where Ar denotes an aromatic heterocyclic group or aromatic carbocyclic group, R denotes a substituent group, Y denotes sulfo or carboxyl, s is an integer from 0 to 5 and r is an integer from 1 to 4. |
