An optical layered body including a light-transmitting substrate and an antiglare layer provided on the light-transmitting substrate. The antiglare layer has a surface roughness on the outermost surface. In the optical layered body, a mean spacing of tops of local peak of profile S is 0.045 mm or more and 0.10 mm or less determined by the procedure disclosed in the specification. The optical layered body can attain properties such as an antiglare property, scintillation prevention and black color reproducibility such as gloss blackness simultaneously.
