LIGHT-ABSORBING ANISOTROPIC FILM, LAMINATE, AND IMAGE DISPLAY DEVICE

WIPO Patent Application WO/2021/246148

A1

The present invention addresses the problem of providing a light-absorbing anisotropic film which enables the production of an image display device having excellent display performance and durability, and a laminate and an image display device in which the light-absorbing anisotropic film is used. This light-absorbing anisotropic film is used in an image display device and is formed using a liquid crystal composition containing a liquid crystal compound and a dichroic substance, and in this light-absorbing anisotropic film, the relationship between the maximum intensity Imax of a signal in the thickness direction of the light-absorbing anisotropic film, the signal originating from the dichroic substance and being detected by time-of-flight secondary ion mass spectrometry, and the intensity Isur1 in the surface of the light-absorbing anisotropic film that corresponds to the viewing side of the image display device satisfies expression (I-1). (I-1): 2.0 ≤ Imax/Isur1
