Abstract
A vacuum envelope of a display apparatus includes a rear plate, a face plate opposing the rear plate, and a side wall interposed between the rear and face plates. A phosphor screen is formed on the inner surface of the face plate. A plurality of electron-emitting elements are provide on the inner surface of the rear plate, to emit electrons to the phosphor screen. A reinforced glass plate is provided, opposing the outer surface of the face plate. A resistive layer is provided between the reinforced glass plate and the face plate. The resistive layer has a sheet resistance of 10 Ω/□ or more and is set at an anode potential.
Claims8
A display apparatus comprising:
- a face plate having a phosphor screen formed on an inner surface of the face plate;
- a rear plate opposing the phosphor screen and having a plurality of electron-emitting elements which emit electrons toward the phosphor screen;
- a transparent insulating substrate opposing an outer surface of the face plate;
- and
- a resistive layer provided between the face plate and the insulating substrate;
- and
- a potential difference between the phosphor screen and the resistive layer is smaller than a potential difference between the resistive layer and the insulating substrate.
