Abstract
The present invention provides a light absorption anisotropic film excellent in adhesiveness to an adjacent layer, and a laminate and an image display device, in which the light absorption anisotropic film is used. The light absorption anisotropic film is formed from a liquid crystal composition that contains a high-molecular weight liquid crystal compound and a dichroic substance, and is a light absorption anisotropic film in which regarding a signal derived from the dichroic substance detected by a time-of-flight secondary ion mass spectrometry, a relationship between a maximum intensity Imax in a thickness direction of a film and an intensity Isur on at least one surface of the film satisfies Expression (I-1) 2≤Imax/Isur.
