A novel optically anisotropic film useful for optical compensation of a liquid crystal display device is provided. An optically anisotropic film comprising at least one compound having a partial structure represented by the following formula (1). In the formula, R 1 , R 2 and R 3 each independently represent a substituent; X is a single bond, —O—, —CO—, —NR 6 — (R 6 is a hydrogen atom, an alkyl group or an aryl group; the represented), - S -, - SO 2 -, - P (= O) (oR 7) - (R 7 represents an alkyl group or an aryl group), a divalent linking group selected from alkylene and arylene groups Or a divalent linking group formed by combining two or more selected from the following linking group group; A represents —COO—, —OCO—, or a substituted or unsubstituted phenylene group, oxadiazole group, or Represents an alkynylene group; Z represents a substituted or unsubstituted alkyl group or an aryl group; n1, n2 and n3 represent an integer of 0 to 4; and l, m and n represent an integer of 0 to 4.
