Claim:
An optical compensation film, comprising: a first optically anisotropic layer, and a second optically anisotropic layer, wherein the first optically anisotropic layer satisfies at least one of the following Expressions (i) to (iii): 1≦Re 1 450)(0°)/Re 1 650)(0°)≦1.25: Equation (i) 1≦Re 1 450)(40°)/Re 1 650)(40°)≦1.25: Equation (ii) 1≦Re 1 450)(−40°)/Re 1 650)(−40°)≦1.25: Equation (iii) in Expressions (i) to (iii), Re 1 λ(θ) is defined as the value of Re retardation in the first optically anisotropic layer determined in the condition that a light of wavelength λ(nm) is entered at an incident angle θ° from the normal line with the retardant phase being defined as the rotation axis, wherein when the values of Re 1 λ(θ) and Re 1 λ(−θ) are different, the magnitude is decided so as to become Re 1 λ(θ)>Re 1 λ(−θ), wherein the first optically anisotropic layer is composed of at least a disc-like liquid-crystal compound, and wherein the disc-like liquid crystal compound comprises at least a compound expressed by the general formula (DI): in general formula (DI), Y 11 , Y 12 and Y 13 represent each independently a methine or nitrogen atom; L 1 , L 2 and L 3 represent each independently a connecting group of single bond or divalent bond; H 1 , H 2 and H 3 represent each independently one expressed by the general formula (DI-A) or (DI-B); R 1 , R 2 and R 3 represent each independently one expressed by the general formula (DI-R); in the general formula (DI-A), YA 1 and YA 2 each represents a nitrogen atom; XA represents an oxygen atom; * indicates a site to bond with L 1 to L 3 ; ** indicates a site to bond with R 1 to R 3 ; in the general formula (DI-B), YB 1 and YB 2 each represents a nitrogen atom; XB represents an oxygen atom; * indicates a site to bond with L 1 to L 3 ; ** indicates a site to bond with R 1 to R 3 ; *-(-L 21 -M) n1 -L 22 -L 23 -Q 1 General formula (DI-R): in general formula (DI-R), * indicates a site to bond with a five-membered ring in general formula (DI); L 21 represents a connecting group of single bond or divalent bond; L 22 represents a divalent connecting group selected from the group consisting of —O—, —O—CO—, —CO—O—, —O—CO—O—, —S—, —NH—, —SO 2 —, —CH 2 —, —CH═CH— and —C≡C—; L 23 represents a divalent connecting group selected from the group consisting of —O—, —S—, —C(═O)—, —SO 2 —, —NH—, —CH 2 —, —CH═CH—, and —C≡C—; M represents a divalent connecting group having at least a cyclic structure; Q 1 represent independently a polymerizable group or hydrogen atom; n1 is an integer of 0 to 4.
