Abstract

See full text

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).
