Transparent laminate and plasma display panel filter utilizing same

摘要

A transparent laminate is constituted by a transparent substrate, a low refractive index transparent thin film formed on a surface of the transparent substrate, between three and five combination layers laminated successively on a surface of the first low refractive index transparent thin film, another high refractive index transparent thin film formed on a surface of the combination layers, and an outermost layer. The combination layers has high refractive index transparent thin films and silver type transparent electrical conductor thin films, each combination layer having one high refractive index transparent thin film and one silver type transparent electrical conductor thin film. The outermost layer is stuck through a transparent adhesive agent layer onto a surface of the high refractive index transparent thin film farthest from the transparent substrate. The outermost layer is at least one of selected from the group of consisting of an anti-reflection film, an anti-mirroring filmanda low reflection anti-mirroring film. The low refractive index transparent thin film is an optically transparent thin film having a refractive index nL in a range of 1.3 to 1.6 and each of the high refractive index transparent thin film is an optically transparent thin film having a refractive index nH in a range of from 1.9 to 2.5.
