MOLD, METHOD FOR MANUFACTURING MOLD, AND ANTIREFLECTIVE FILM

摘要

This antireflective film (32A) has a plurality of first protrusions (32a) which, viewed from the direction of the normal line of the surface, has a two-dimensional size of 50 nm to less than 300 nm, and a height of 50-300 nm. The plurality of first protrusions (32a) include a plurality of ring-shaped protrusion groups in each of which a plurality of the first protrusions (32a) are arrayed in a ring shape at interproximal distances of 50 nm to less than 300 nm. A plurality of areas respectively enclosed by the plurality of ring-shaped protrusion groups include a plurality of first regions (R1) in which the average value of the major axis and the minor axis is more than 300 nm but not more than 800 nm.
