Abstract
This method of manufacturing an optical laminate comprising a transparent substrate, an adhesion layer, an optical functional layer, and an antifouling layer laminated in this order, includes an adhesion layer forming step of forming the adhesion layer, an optical functional layer forming step of forming the optical functional layer, a surface treatment step of treating the surface of the optical functional layer so that the rate of change in surface roughness represented by formula (1) is 1˜25%, and an antifouling layer forming step of forming the antifouling layer on the surface-treated optical functional layer; Rate of change of surface roughness (%)=((Ra2/Ra1)−1)×100(%) Formula (1) (Formula (1), where Ra1 represents the surface roughness (Ra) of the optical functional layer before the surface thereof is treated, and Ra2 represents the surface roughness (Ra) of the optical functional layer after the surface thereof is treated.).
