Abstract:
Provided are an optically anisotropic film which has excellent moisture-heat resistance and can have a reduction in the thickness, an optical film, a polarizing plate, and an image display device. The optically anisotropic film is obtained by polymerizing a polymerizable liquid crystal composition, in which the polymerizable liquid crystal composition contains a polymerizable liquid crystal compound represented by Formula (1): L1-SP1-(E3-A1)m-E1-G1-D1-Ar1-D2-G2-E2-(A2-E4)n-SP2-L2 and a polymerizable liquid crystal compound represented by Formula (2): L1-SP1-(E3-A1)m-E1-G1-D1-Ar2-D2-G2-E2-(A2-E4)n-SP2-L2, and the optically anisotropic film satisfies Formula (3): Re(450)/Re(550)
