Abstract
An image forming apparatus includes a first substrate on which a plurality of electron-emitting devices and drive wiring for driving the plurality of electron-emitting devices are arranged, and a second substrate on which an image forming member and lead wiring connected to the image forming member are arranged. The first and second substrates are disposed in opposition to each other, and the plurality of electron-emitting devices, the drive wiring, the image forming member and the lead wiring are disposed within an envelope which is formed between the first and second substrates. The lead wiring extends to a corner of the first substrate and is in contact with an electroconductive terminal, and the electroconductive terminal extends from a contact portion with the lead wiring toward the first substrate and is partially exposed outside of the envelope through an opening formed in the first substrate. In addition, a wiring of a defined potential is disposed between the opening and the driving wiring in the envelope.
