Title:
ELECTRON EMITTING ELEMENT, ELECTRON EMITTING DEVICE, DISPLAY AND LIGHT SOURCE
Document Type and Number:
WIPO Patent Application WO/2006/070446
Kind Code:
A1
Abstract:
An electron emitting element (10A) is provided with a lower electrode (16) formed on a glass substrate (11); an emitter part (12) composed of a dielectric film formed on the lower electrode (16); and an upper electrode (14) formed on the emitter part (12). A driving voltage (Va) for electron emission is applied between the upper electrode (14) and the lower electrode (16). At least 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 (26a) facing the emitter part (12) at a circumference part (26) of the penetrating part is separated from the emitter part (12).
