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, &thetas;a 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, &thetas;a represents the average inclination angle of the concavoconvexes, and Rz represents the average roughness of the concavoconvexes. |
