A light absorption anisotropic layer, manufacturing thereof, a laminate and an image display device. The layer contains a dichroic substance and a liquid crystal compound, in which, when, in an X-ray diffraction pattern measurement using an in-plane diffraction method with X-ray irradiation, diffracted X-rays are measured in a measurement region of a rotation angle φ in in-plane direction of light absorption anisotropic layer: 0° to 180° and a diffraction angle 2θ:0° to 10° to determine a diffraction angle 2θmax and a rotation angle φmax at which a peak intensity is maximized, a peak intensity of diffracted X-rays at the diffraction angle 2θmax and the rotation angle φmax is represented by I(φmax), and a peak intensity of diffracted X-rays at the diffraction angle 2θmax and the rotation angle φmax−10° is represented by I(φmax−10), a relationship expressed by Expression (1) I(φmax)/I(φmax−10)≥1.6 is satisfied.
