Title:
ELECTRON EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2006/075407
Kind Code:
A1
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).
