Original Abstract Submitted

A light absorption anisotropic layer used in a viewing angle control system which has high image visibility from a desired direction and can sufficiently block images from other directions, an optical film, a viewing angle control system, and an image display device using the light absorption anisotropic layer. The light absorption anisotropic layer is formed of a liquid crystal composition containing a liquid crystalline compound, a dichroic substance, and an alignment agent, in which a content of the dichroic substance is 8.0% by mass or more with respect to a total solid content mass of the liquid crystal composition, and an angle θ between a transmittance central axis of the light absorption anisotropic layer and a normal direction of a surface of the light absorption anisotropic layer is 5° or more and less than 80°.
