Abstract
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 substratea bottom electrodea tunneling insulatorand a top electrodeare prepared. On a lower layer of the top electrodea top electrode bus lineis formed, and the top electrodeis reliably connected to the top electrode bus linevia a contact electrodeA field insulatorA, a lower layerof the interlayer insulator deposited by sputtering and an upper layerof the interlayer insulator are laminated between the top electrodeand the contact electrode and the bottom electrodeand the bottom electrodeis insulated from the top electrode(top electrode bus line).
