Abstract
An electron emission element (20) includes a first electrode (30a) and a second electrode (40) which are arranged facing each other, an intermediate layer (50) that is provided between the first electrode (30a) and the second electrode (40), and an insulating layer (60) that is formed with a thickness d1 on a substrate (30). A level difference between the insulating layer (60) and the first electrode (30a) is smaller than the thickness d1 of the insulating layer (60).
Claims11
An electron emission element that applies voltage across a first electrode and a second electrode which are arranged facing each other and emits electrons from the second electrode, the electron emission element comprising:
- an intermediate layer that is provided between the first electrode and the second electrode;
- and
- an insulating layer that is formed with a thickness d1 on a substrate provided with the first electrode, wherein
- the intermediate layer has conductive fine particles dispersed, and
- a level difference d2 between the insulating layer and the first electrode is smaller than the thickness d1 of the insulating layer.
