Abstract

In the image display apparatus using the electron-emitting device, wiring metal is prevented from being diffused to a fine particle when a fine particle dispersed film is disposed on the wiring, and the image characteristic is prevented from being degraded because of the diffusion. A first wiring 4 and a second wiring 6 intersecting with the first wiring 4 through an insulating layer are formed on an insulation substrate 1, and after an electroconductive shielding layer 7 is formed on the second wiring 6, a anti static film made of a fine particle dispersed film is formed.
