Title: Optical compensatory sheet, elliptical polarizing plates and liquid-crystal display

Abstract: A novel optical compensatory sheet is disclosed. The sheet comprises an optically anisotropic layer comprising at least one compound selected from the group represented by Formula (I): ##STR00001## where L.sup.1, L.sup.2 and L.sup.3 respectively represent a single bond, NR.sup.a, where R.sup.a is a hydrogen atom (H), an optionally substituted alkyl or aryl group, oxygen atom (O) or sulfur atom (S); A.sup.1, A.sup.2 and A.sup.3 respectively represent an alkylene group; R.sup.1, R.sup.2 and R.sup.3 respectively represent a substituent group; m.sup.1, m.sup.2 and m.sup.3 respectively represent an integer not less than 0, at least one of m.sup.1, m.sup.2 and m.sup.3 is not 0, when m.sup.1 and m.sup.2 are 0, L.sup.3 represents NH or S; and when m.sup.1, m.sup.2 and m.sup.3 are respectively not less than 2, plural A.sup.1, A.sup.2 or A.sup.3 may be same or different each other.
