Abstract
A filter for a plasma display panel wherein the filter has a laminated body, as a constituent element, in which n units (3≦n≦10) each consisting of a metallic oxide film and a silver transparent electric-conductor film are successively laminated unit after unit on a surface of a transparent film base, and a metallic oxide film is formed on the units as an outermost layer of the laminated body, each metallic oxide film having optical transparency of a refractive index of 1.5 to 2.7, each silver transparent electric-conductor film having a thickness set substantially to a fixed value in a range of from 5 to 20 nm, each of the metallic oxide film put directly on the surface of the base and the outermost-layer metallic oxide film having a thickness 5/2 (1±0.15) times as large as the thickness of each silver transparent electric-conductor film, each of the other metallic oxide films located halfway between the metallic oxide film put directly on the surface of the base and the outermost-layer metallic oxide film having a thickness 5 (1±0.15) times as large as the thickness of each silver transparent electric-conductor film.
