Abstract:
In order to improve the scratch resistance of an antireflective article having a moth-eye structure, an antireflective article is provided that has fine protrusions densely arranged therein, and has the interval between adjacent fine protrusions being no more than the shortest wavelength in the wavelength band for antireflection. At least some of the fine protrusions are fine protrusions having a plurality of apexes.
