Abstract
Provided is an optical laminate including an optically anisotropic layer having at least two regions having different visibility correction transmittances, in which the visibility correction transmittance in a region having a high transmittance is further improved. An optical laminate including: at least a first region and a second region having different values of visibility correction transmittance; and a protective layer having a thickness of 5 μm or less, an orientation layer, and a light absorption anisotropic layer provided in this order, wherein the second region is a region in which the visibility correction transmittance is higher than that of the first region, and the light absorption anisotropic layer is a layer including a liquid crystal composition containing a dichroic dye, and includes the first region and the second region.
