The present invention provides an image display device, by which it is possible to prevent dielectric breakdown between a bottom electrode and a top electrode (top electrode bus line), which make up thin-film type electron sources, and which is free of display defect and has longer service life. On a cathode substrate 10, a bottom electrode 11, a tunneling insulator 12, and a top electrode 13 are prepared. On a lower layer of the top electrode 13, a top electrode bus line 16 is formed, and the top electrode 13 is reliably connected to the top electrode bus line 16 via a contact electrode 15. A field insulator 12A, a lower layer 14a of the interlayer insulator deposited by sputtering and an upper layer 14b of the interlayer insulator are laminated between the top electrode 13 and the contact electrode and the bottom electrode 11, and the bottom electrode 11 is insulated from the top electrode 13 (top electrode bus line 16).
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:
