Electron-emitting device and process for making the same
First Claim
1. An electron-emitting device comprising;
- a plurality of electrically insulating substrates, each having at least an upper face, said upper face of each said substrates defining a common plane;
an intermediate layer interposed between successive substrates, said intermediate layer being recessed from said common plane;
a cathode layer material provided within said intermediate layer at a middle portion thereof and extending from said intermediate layer adjacent to said common plane; and
a gate electrode provided on said upper face of each of said plurality of substrates.

Abstract
An electron-emitting device including; electrical insulating substrates (1); an intermediate layer having a metal layer (2) and an insulating material layer (3) or having an insulating material layer (3), superposed in the thickness direction of said electrical insulating substrates (1) so as to be provided between said electrical insulating substrates (1) in the manner that it is recessed from one side surfaces of said electrical insulating substrates (1); a cathode material (4) provided at the middle portion of said intermediate layer, one end of said cathode material (4) protruding from the insulating material layer (3) that constitutes said intermediate layer; and a gate electrode (5) provided on said electrical insulating substrate (1) on the side where said intermediate layer is recessed.
