光吸収異方性層、光学フィルム、視野角制御システムおよび画像表示装置

Abstract

The present invention addresses the problem of providing a light-absorption anisotropic layer used in a viewing angle control system whereby visibility of an image from a desired direction is high and the image is adequately blocked from other directions, and an optical film, a viewing angle control system, and an image display device that use the light-absorption anisotropic layer. This light-absorption anisotropic layer is formed from a liquid crystal composition that contains a liquid crystalline compound, a dichroic substance, and an alignment agent, the content of the dichroic substance being 8.0 mass% or greater with respect to the mass of the total solid content of the liquid crystal composition, and the angle θ formed by the center axis of transmittance of the light-absorption anisotropic layer and the normal direction of the surface of the light-absorption anisotropic layer being 5° to less than 80°.
