PURPOSE:To suppress color of reflecting light interfering with the view while sufficiently obtaining a reflection preventing effect. CONSTITUTION:A device comprises a glass-made face panel 1, conductive thin film of high refractive index as the first layer 2 formed on an external surface of this glass-made face panel and a reflection preventing Film formed of a low refractive index thin film as the second/third layers 3, 4 laminated on this high refractive index thin film and further having many protrusions and hollows in an exposed surface. The reflection preventing.film has a reflection characteristic where a visual refractive index of mirror surface reflecting light is 1.5% or less and also a refractive index with a 436nm wavelength in a mirror suface reflection spectrum is 3% or less. |
