Abstract
An object of the present invention is to provide an antireflective film having an anti-reflection function with which reflection of incident light from external can be further reduced and a high-visibility display device having such an antireflective film. The tops of the plurality of pyramidal projections are evenly spaced and each side of the base of a pyramidal projection is in contact with one side of the base of an adjacent pyramidal projection. That is, one pyramidal projection is surrounded by other pyramidal projections, and the base of the pyramidal projection and the base of the adjacent pyramidal projection have a side in common.
