ABSTRACT:
A vacuum envelope of an image display apparatus has a rear substrate and a front substrate, which are opposed to each other, and a plurality of electron emitting elements are located in the vacuum envelope. The respective peripheral portions of the front substrate and the rear substrate are sealed together with a sealing layer between them. A diffusion layer that contains a component of the sealing layer is formed on the substrate side of an interface between the sealing layer and the front substrate and/or the rear substrate.
