Abstract
The evacuated envelope of an image display apparatus has a rear substrate, a front substrate opposing the rear substrate, and a sidewall interposed between the rear and front substrates. A phosphor screen is formed on the inner surface of the front substrate. Electron-emitting elements are provided on the rear substrate. An indium layer is formed on a sealing surface lying between the front substrate and the sidewall. When the indium layer is heated and melted in a vacuum atmosphere, the front and rear substrates are sealed to each other, with the sidewall interposed between them.
