Abstract
A method for producing an optical layered body which can attain properties such as an antiglare property, scintillation prevention and black color reproducibility such as gloss blackness simultaneously, and a production apparatus of the optical body are provided. The method includes forming an antiglare layer having a surface roughness on the light-transmitting substrate, wherein with respect to the surface roughness, when denoting a mean spacing of profile irregularities of the surface of the optical layered body by Sm, a mean inclination angle of profile irregularities by θa, and mean roughness of the surface roughness by Rz, Sm is 50 μm or more and less than 100 μm, θa is 0.1° or more and 1.0° or less, and Rz is more than 0.2 μm and 1.0 μm or less.
