Abstract:
An optical laminate having a light transparent base material and an anti-dazzling layer provided on the light transparent base material, wherein the outermost surface of the anti-dazzling layer has a concavoconvex surface. The concavoconvex shape simultaneously satisfies the following formulae (I) 1.2≦θa≦2.5 and (II) 0.004≦ψ≦0.18, wherein θa represents the average inclination angle of the concavoconvex part; Rz represents the average roughness of concavoconvexes; Sm represents the average spacing of the concavoconvexes; and ψ represents the ratio, between Rz and Sm, defined by ψ=Rz/Sm. The optical laminate has an internal haze value of not less than 0% and not more than 50%, and the optical laminate has a surface haze value of not less than 0.5% and not more than 4.5%.
