Abstract
To provide an antireflection member which not only has a low reflectance, but also is enhanced in scratch resistance, and an image display device comprising the antireflection member. An antireflection membercomprising a low refractive index layeron a transparent substrate, in which the low refractive index layerincludes a binder resin and silica particlesand, a ratio of Si element attributed to the silica particles, obtained by analysis of a surface region of the low refractive index layerby X-ray photoelectron spectroscopy, is 10.0 atomic percent or more and 18.0 atomic percent or less and a ratio of C element under the assumption that the ratio of Si element is defined to be 100 atomic percent is 180 atomic percent or more and 500 atomic percent or less.
