ABSTRACT:
A anti-reflection member provided with an antistatic function and an electromagnetic radiation shielding function and having a reflection preventing optical thin film excellent in adhesion with the hard coat layer.
The anti-reflection member comprises a laminate composed of substrate, hard coat layer, and reflection preventing optical thin film having at least two layers, the first layer of the reflection preventing optical thin film provided in contact with the hard coat layer comprises a transparent conductive oxide film (for example, SnO.sub.2, ZnO, In.sub.2 O.sub.3, or ITO) formed by reactive physical vapor phase deposition, and the second layer of the reflection preventing optical thin film consists of a material (for example, SiO.sub.2 or MgF.sub.2) having a refractive index smaller than that of the first layer.
