OPTICAL LAMINATE, POLARIZING PLATE, IMAGE DISPLAY DEVICE, AND METHOD FOR MANUFACTURING OPTICAL LAMINATE

WIPO Patent Application WO/2022/259847

A1

[Problem]To improve abrasion resistance while maintaining an antiglare property. [Solution] An optical laminate 10 is provided with a transparent substrate 11, at least one hard coat layer 12 provided on the transparent substrate 11 and comprising a resin composition, and at least one metal-oxide layer (adhesion layer 13, antireflection layer 14) provided on the hard coat layer 12 and comprising a metal oxide. A structure with recesses and protrusions is formed on the surface on the metal-oxide layer side of the hard coat layer 12, and the height distribution of the surface of the structure with recesses and protrusions satisfies expression (1).　(1): A/1.9 < P where A is the height of the highest point of the surface of the structure with recesses and protrusions when the height B of the lowest point of the surface of the structure with recesses and protrusions is defined as 0, and P is the mode of the height distribution of the surface of the structure with recesses and protrusions when the height B of the lowest point of the surface of the structure with recesses and protrusions is defined as 0.
