Abstract: Provided is a light absorption anisotropic film capable of preparing an image display device having excellent display performance and excellent durability, and a laminate and an image display device formed of the light absorption anisotropic film. The light absorption anisotropic film is used for an image display device, which is formed of a liquid crystal composition containing a liquid crystal compound and a dichroic substance, in which in a signal derived from the dichroic substance detected by time-of-flight secondary ion mass spectrometry, a relationship between a maximum intensity Imax of the light absorption anisotropic film in a thickness direction and an intensity Isur1 in a surface of the light absorption anisotropic film on a viewing side of the image display device satisfies Expression (I-1) 2.0≤Imax/Isur1.
