摘要
There is provided a method for manufacturing an optical laminate in which properties such as a glare-proof property, an antidazzle property, and a black reproducible property for obtaining, for example, glossy black, can be simultaneously obtained. Manufacturing equipment for the optical laminate is also provided. The method for manufacturing an optical laminate having a light-transmitting substrate and a glare-proof layer formed on the light-transmitting substrate comprises a step of forming the glare-proof layer having an uneven shape on the light-transmitting substrate. When an average pitch of the surface unevenness of the optical laminate is denoted by Sm, an average slope angle of the unevenness by θa, and an average roughness of the unevenness by Rz, the uneven shape satisfies the following conditions: Sm is greater than or equal to 50 μm and less than 100 μm; θa is greater than or equal to 0.1 degrees and less than or equal to 1.0 degree; and Rz exceeds 0.2 μm and is less than or equal to 1.0 μm.
