Claim 6:
7. A laminate used for an image display device, comprising in order:
a base material;
an alignment film; and
a light absorption anisotropic film,
wherein the light absorption anisotropic film is the light absorption anisotropic film according to claim 1, and
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  (I-1).
