By finding the surface shape and the physical properties required for a structure having antireflection performance of light, improving the permeability of light, etc., it is possible to provide a structure having particularly imparted surface scratch resistance, and to form a structure having such a specific structure and physical properties. It provides a composition which can provide the composition which can provide the structure with a large aspect ratio which is more excellent in the anti-reflective performance of a light, or a transmission improvement performance. That is, as a structure having a convex portion having an average height of 100 nm or more and 1000 nm or less or a concave portion having an average depth of 100 nm or more and 1000 nm or less, the convex portion or concave portion having an average period of 100 nm or more and 400 nm or less with respect to at least one direction. The structure is a structure in which the (meth) acrylic polymerizable composition is polymerized by light irradiation, electron beam irradiation, and / or heating, and the storage modulus at 180 ° C or higher is 0.5 GPa or more. |
