Abstract
An optical laminate includes a translucent substrate, and at least one optical functional layer provided on the translucent substrate. The optical functional layer has a concave-convex shape on at least one surface. The optical functional layer contains two types of inorganic fine particles, and resin particles. The optical laminate has an internal haze X and a total haze Y satisfying (1) Y>X, (2) Y≤X+25, (3) Y≤50, and (4) 7≤X≤25. The optical laminate has a transmitted image clarity of 15% to 55% as measured using a 0.5-mm width optical comb. The number of projections having a height of not smaller than 0.1 μm is not less than 900 per mm2 of measurement area in the concave-convex shape as measured by optical interferometry at an outermost surface of the optical functional layer.
