Image display apparatus

Abstract

The present invention provides an image display apparatus which reduces electrical discharges produced by electron-emitting devices (13) and prevents image degradation during discharge. The image display apparatus includes a rear plate equipped with information wirings (10), scan wirings (12), an insulating layer (11) and electron-emitting devices (13); and a face plate placed opposite to the rear plate and equipped with an anode and light emitting members, wherein the electron-emitting devices are placed between first (12a) and second (12b) scan wirings adjacent to each other, and are electrically connected to the first scan wiring, the second scan wiring is electrically connected to a discharge induction electrode (9) via a contact hole (15) which penetrates the insulating layer (11), one end of the discharge induction electrode is covered with the insulating layer (11), and the other end extends out from the insulating layer in a direction toward the electron-emitting devices (13).

Description

technical field [0001] The present invention relates to a flat panel image display device using electron-emitting devices. Background technique [0002] Conventionally known flat-panel image display devices using electron-emitting devices include image display devices comprising an electron source substrate (back plate) and a counter substrate (front plate) placed opposite to each other, wherein the electron source substrate A large number of electron-emitting devices are formed on the counter substrate, and the anode and the light emitting part are mounted on the counter substrate. In this image display device, electrons are emitted from the electron-emitting devices when a voltage is applied between the gate electrode and the cathode electrode of the electron-emitting devices. The emitted electrons are directed to the light emitting part to emit light. In doing so, it is desirable to increase the difference between the anode potential and the cathode-gate electrode poten...

Problems solved by technology

This lowers the driving voltage of the electron-emitting device, causing image degradation during discharge

[0005] In addition, with the technology disclosed in Japanese Patent Application Laid-Open No. 2006-209990, an additional electrode placed on the insulating layer is allowed to have a smaller area than the insulating layer, and thus cannot be placed close to the electron-emitting device.

This makes it difficult for the additional electrode to act as a lightning protection device, which in turn makes it impossible to reduce the discharge generated by the electron-emitting device
