PURPOSE: An optical laminate and manufacturing method thereof, and a polarizing plate and display device using the same are provided to increase anti-glare property and a contrast. CONSTITUTION: An optical function layer(20) is placed on a light-transmitting base object(10). The optical function layer has a domain structure. The film thickness of the optical function layer is D. The average particle diameter of a light transmitting fine particle is r'. D and r' satisfy 3 x r<D<=10 x r.
