Provided is a composition for an anisotropic optical film, which is capable of producing an anisotropic optical film that can obtain good diffusivity and has an excellent view angle enlargement when used in a display device. A composition for an anisotropic optical film, which is characterized by containing (A) a (meth) acrylate having a refractive index nA of 1.50-1.65 and having one or more aromatic rings and (meth) acryloyl groups, (C) a polymerization initiator, and (D) a polymerization inhibitor having a structure in which a carbonyl group or a hydroxyl group is added as a substituent of a conjugated ring compound, the content of the component (C) is 0.1-20 parts by weight per 100 parts by weight of the non-volatile component of the composition, and the content of the component (D) is 0.001-1 part by weight per 100 parts by weight of the non-volatile component of the composition. 本发明提供一种各向异性光学膜用组合物，其能够制造可得到良好的扩散性且用于显示装置时的视角扩大优异的各向异性光学膜。一种各向异性光学膜用组合物，其特征在于，包含(A)成分：折射率nA为1.50～1.65且具有1个以上芳香环及(甲基)丙烯酰基的(甲基)丙烯
