Abstract

An electron emitting element (10A) is provided with an emitter part (12) composed of a dielectric material, and an upper electrode (14) and a lower electrode (16) whereupon a driving voltage (Va) is applied for electron emission. The upper electrode (14) is formed on an upper plane of the emitter part (12), and the lower electrode (16) is formed on a lower plane of the emitter part (12). The upper electrode (14) is provided with a plurality of penetrating parts (20) from which the emitter part (12) is exposed. In the upper electrode (14), a plane facing the emitter part (12) at a circumference part (26) of the penetrating part (20) is separated from the emitter part (12).

Description

technical field

[0001] The present invention relates to an electron emission element having a first electrode and a second electrode formed on a substance forming an emitter. Background technique

[0002] Currently, an electron emission device has a cathode electrode and an anode electrode, and is used in various applications such as a field emission display (FED) or a backlight. When used in an FED, a plurality of electron emission elements are arranged two-dimensionally, and a plurality of phosphors facing these electron emission elements are arranged at predetermined intervals.

[0003] Conventional examples of this electron emission element include, for example, Patent Documents 1 to 5, but they have the following problems: because none of them use a dielectric for the material forming the emitter, forming or micromachining is required between opposing electrodes, A high voltage must be applied for electron emission, and the panel manufacturing process is complicated an...
