Patent ID: 8259259

Claim:
An optically anisotropic film comprising at least one species of liquid crystal compound which exhibits a nematic phase or a smectic phase, the liquid crystal phase showing birefringence Δn(λ) at wavelength λ which satisfies the numerical expression (1) below Δ n (450 nm)/Δ n (550 nm)<1 (1) wherein molecules of the liquid crystal compound are fixed in a state of tilted alignment in the optically anisotropic film, and wherein the liquid crystal compound is a compound represented by the formula (I) below: where, each of A 1 and A 2 independently represents a group selected from the group consisting of —O—, —NR— (R represents a hydrogen atom or substituent), —S— and —CO—; Z represents one or two atoms selected from the group consisting of carbon atom, and the Group XIV to XVI non-metallic atoms, and forms a five- or six-membered ring together with C—C═C—C or C═C—C═C in the formula; each of R 1 , R 2 and R 3 independently represents a substituent; m represents an integer from 0 to 4; each of L 1 and L 2 independently represents a single bond or divalent linking group; X represents any of the Group XIV to XVI non-metallic atoms, to which a hydrogen atom or substituent R 4 may be bound; and at least one of R, R 1 , R 2 , R 3 and R 4 has a polymerizable group.
