Abstract:
Provided is a fine concave-convex laminate that is reduced in thickness, has excellent antireflection performance, and can suppress scattering and absorption of short-wavelength light. A fine concave-convex laminate comprises a substrate, a first transparent organic layer, and a second transparent organic layer laminated in the stated order, wherein the first transparent organic layer has a fine concave-convex structure at a surface facing the second transparent organic layer, the second transparent organic layer has fine concave-convex structures at both surfaces, and a thickness of a composite layer composed of the first transparent organic layer and the second transparent organic layer is 15 μm or less.
