Electron-emitting device and method of manufacturing the same and display apparatus using the same

A display apparatus comprising;

• a first substrate and a second substrate facing each other with a vacuum space therebetween;
• a plurality of electron-emitting devices provided on said first substrate;
• a collector electrode provided on an interior surface of said second substrate;
• and
• a phosphor layer formed on said collector electrode;
• wherein each of said electron-emitting devices comprises
• an electron source layer made of one of a metal, a metal alloy and a semiconductor formed on an ohmic electrode,
• an insulating layer formed on said electron source layer and having at least one island region serving as an electron-emitting section in which film thickness of said insulating layer is reduced,
• a metal thin film electrode formed on said insulating layer, and
• a carbon region made of one of carbon and a carbon compound is provided on at least one of a bottom and inside of said island region, the carbon region being disposed having a vacuum space directly over the carbon region,
• wherein the electron source layer directly interfaces the carbon region at a center of the island region with the electron source layer facing the vacuum space via the carbon region at the center of the island region.
