摘要:
An optical laminate is provided which has anti-dazzling properties and can realize excellent glare preventive properties and black reproducibility (gradation rendering of black at low brightness). The optical laminate includes a light transparent base material and an anti-dazzling layer or a light diffusion layer provided on the light transparent base material, wherein the outermost surface of the anti-dazzling layer or light diffusion layer has a concavoconvex surface. The anti-dazzling layer satisfies the requirements that Sm is not less than 100 μm and not more than 600 μm, θa is not less than 0.1 degree and not more than 1.2 degrees, and Rz is more than 0.2 μm and not more than 1 μm, wherein Sm represents the average spacing of concavoconvexes in the anti-dazzling layer, θa represents the average inclination angle of the concavoconvexes, and Rz represents the average roughness of the concavoconvexes.
