Abstract: A light absorption anisotropic layer which has high contrast and can suppress hue change of an image reflected by surroundings relative to an original image when used in a viewing angle control system, an optical film using the light absorption anisotropic layer, a viewing angle control system, and an image display device. The light absorption anisotropic layer is formed of a liquid crystal composition containing a liquid crystalline compound, a dichroic substance, and an alignment agent. The liquid crystalline compound is in a liquid crystal state of a smectic phase, a content of the dichroic substance is 5.0% 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 between 0° and 45°.

Abstract: An image projection system in which a projection image is easier to see. An image projection system includes an image projection device which emits projection light that is linearly polarized light; a screen which is irradiated with the projection light emitted from the image projection device; and a light absorption anisotropic layer which is disposed between the image projection device and the screen and through which the projection light passes, the light absorption anisotropic layer contains a dichroic substance, and a transmittance central axis of the light absorption anisotropic layer is in a direction toward the screen.

Abstract: Provided is a laminate capable of reducing a change in hue of a reflected image in the surroundings (for example, window glass) from an original image, suppressing a hue shift of particularly the reflected image to redness, and suppressing the reflected image from being conspicuous, a reflection prevention system including this laminate, and an image display device including this laminate. The laminate includes a polarizer having an absorption axis in an in-plane direction, a light absorption anisotropic layer containing a liquid crystal compound and a dichroic substance, and a linear polarization conversion layer, in which an angle between a transmittance central axis of the light absorption anisotropic layer and a normal line of a layer plane of the light absorption anisotropic layer is 0° or greater and 45° or less.
