ABSTRACT:
In a conductive antireflection film having predetermined optical characteristics, of the layers of the conductive antireflection film, two layers located on the transparent substrate side are replaced with a three-layered film having a metal oxide film as an intermediate layer thereof. In this three-layered film when k.sub.i =4n.sub.i d.sub.i .lambda..sub.0 (where n.sub.i is the refractive index of the ith layer, di is the geometric thickness of the ith layer, and .lambda..sub.0 is a middle wavelength in design), the metal oxide film as the second layer satisfies k.sub.2 .gtoreq.0.01, and an ITO film as the first layer satisfies k.sub.1 .gtoreq.0.1.
