Patent ID: 7442961

Claim:
An image display device provided with a vacuum panel container, comprising a cathode substrate where a plurality of thin-film type electron sources are arranged with predetermined spacing, an anode substrate where spot-like or linear phosphor films are arranged to face to each other, a plurality of spacers for supporting said cathode substrate and said anode substrate with predetermined spacing, and a frame glass for maintaining vacuum condition, wherein there are provided a plurality of electric bus lines extending in row direction and in column direction crossing perpendicularly via an interlayer insulator, and said thin-film type electron sources are connected with said electric bus lines in column direction and in row direction at positions corresponding to each of intersection coordinates, and an image is displayed by line-sequentially driving said thin-film type electron sources, wherein: said electron source is a cold cathode type electron source which comprises a bottom electrode, a top electrode, and an electron accelerator interposed between said two electrodes; and said interlayer insulator is disposed between said bottom electrode and said bus line and comprises at least two layers of thin-film lamination including one layer of a thin-film insulating material formed by film coating and having a specific dielectric constant of not more than 5 and another layer of a thin-film insulating material deposited under vacuum condition.
