Abstract
The present invention provides a A light absorption anisotropic film that, in a case of being applied to an image display device, it is possible to suppress redness of an image originating from the image display device, which is reflected on surrounding members arranged around the image display device; and an optical film and an image display device. The light absorption anisotropic film of the present invention is a light absorption anisotropic film is formed of a composition containing a liquid crystal compound and a dichroic substance, in which the light absorption anisotropic film has two main surfaces facing each other, an angle between a normal direction of the main surface of the light absorption anisotropic film and a transmittance central axis of the light absorption anisotropic film is 0° to 45°, and predetermined requirements are satisfied depending on the angle.
