Abstract
On the outer surface of a glass face panel 1 of a display device, a first layer 2 of an electrically conductive transparent thin film having a high refractive index, and a second layer 3 and a third layer 4 having a low refractive index are deposited as an anti-reflection film. The first layer 2 is formed to have a thickness in a range of 10-20 nm, whereby the surface of the anti-reflection film has a luminous reflectance of 1.5% or less, and a reflectance of 3% or less at a wavelength of 436 nm most prominent light of blue.
