| 发明名称 | Electron emitting element and method for producing the same | ||
| 摘要 | The present invention provides an electron emitting element, comprising: a first electrode; an insulating layer formed on the first electrode and having an opening of through hole; a second electrode formed on the insulating layer, the second electrode being disposed so as to cover at least the opening and face the first electrode via the opening; and a fine particle layer disposed between the first electrode and the second electrode, the fine particle layer being composed of insulating fine particles and conductive fine particles, wherein the insulating layer is disposed between the first electrode and the fine particle layer, or between the second electrode and the fine particle layer, when a voltage is applied between the first electrode and the second electrode, electrons are emitted from the first electrode and accelerated in the fine particle layer to pass through the second electrode. | ||

| 主权项 | 1. An electron emitting element, comprising: a first electrode; an insulating layer formed on the first electrode and having an opening of through hole; a second electrode formed on the insulating layer, the second electrode being disposed so as to cover at least the opening and face the first electrode via the opening; and a fine particle layer disposed between the first electrode and the second electrode, the fine particle layer being composed of insulating fine particles and conductive fine particles, wherein the insulating layer is disposed between the first electrode and the fine particle layer, or between the second electrode and the fine particle layer, when a voltage is applied between the first electrode and the second electrode, electrons are emitted from the first electrode and accelerated in the fine particle layer to pass through the second electrode, the fine particle layer is disposed on the opening, and the second electrode is disposed on the insulating layer so that edges thereof do not coincide with edges of the opening and overlap the insulating layer. | ||
