Abstract:
An electron emission device based flat panel display apparatus comprising:a back substrate and an optically transparent front substrate opposing each other with a vacuum space interposed therebetween;a plurality of electron emission devices, each of said electron emission devices including an electron-supply layer made of metal or semiconductor formed on ohmic electrodes which are formed on a surface of said back substrate proximate to said vacuum space, an insulator layer formed on said electron-supply layer, and a thin-film metal electrode formed on said insulator layer and facing said vacuum space;said front substrate including collector electrodes formed on its surface proximate to said vacuum space, fluorescent material layers formed on said collector electrodes, and an image display array comprised of a plurality of light emitting elements corresponding to said fluorescent material layers;insulative support members formed on said back substrate and disposed between adjacent ones of said electron emission devices; anda plurality of electrodes, each of said electrodes disposed between adjacent ones of said thin-film metal electrodes and on said insulative support members for electrically connecting said thin-film metal electrodes.
