Abstract

Official abstract text for this publication.

Disclosed is a tabular member that has an excellent low reflectivity and that can reduce coloring due to reflected light. In at least one example embodiment, specifically disclosed is a tabular member which comprises a base, a first antireflective film disposed on a surface of the base, and a second antireflective film disposed on the other surface of the base. The first and second antireflective films each have a plurality of projections on the surface thereof, and the distances between the apexes of two adjacent projections are shorter than or equal to the wavelength of visible light. The light obtained by combining the light reflected from the surface of the first antireflective film and the light reflected from the surface of the second antireflective film together has flat wavelength dispersion within the range of visible light.

First claim
