1. An electron emitter comprising:
- a first electrode formed on a glass substrate;
an emitter section made of a dielectric film formed on said first electrode;
a second electrode formed on said emitter section, wherein a drive voltage for electron emission is applied between said first electrode and said second electrode;
at least said second electrode has a plurality of through regions through which said emitter section is exposed; and
said second electrode has a surface which faces said emitter section in peripheral portions of said through region and which is spaced from said emitter section.

Abstract
An electron emitter includes a lower electrode formed on a glass substrate, an emitter section made of dielectric film formed on the lower electrode, and an upper electrode formed on the emitter section. A drive voltage for electron emission is applied between the upper electrode and the lower electrode. At least the upper electrode has a plurality of through regions through which the emitter section is exposed. The upper electrode has a surface which faces the emitter section in peripheral portions of the through regions and which is spaced from the emitter section.
