Abstract
A flat vacuum envelope is provided where an anode electrode is conductively connected to the contact portion of a high-voltage supplying lead with high reliability so that the connection electrode plate is not stripped from the anode electrode ( ). A field emission region ( ), which is formed of a gate layer and emitters, is laminated on a first glass electrode ( ). An anode electrode ( ), which is formed of a fluorescent display substance and a transparent electrode, is laminated on a second glass substrate ( ). An exhaust tube ( ) is formed to the first glass substrate ( ) to evacuate the inside of the vacuum envelope. The lead ( ) is connected to the anode electrode ( ) via the connection anode plate ( ). The connection anode plate ( ) is joined to the anode electrode ( ) by the resilient member ( ) so that the conductivity thereof is not impaired while the exhaust tube ( ) is being sealed.
