    摘要： An electron emission device includes: a semiconductor layer; a porous semiconductor; and a thin-film metal electrode which are layered in turn. The electrode faces a vacuum space. The porous semiconductor layer has at least two or more of porosity-changed layers which have porosities which are different from each other in the thickness direction. The electron emission device emits electrons when an electric field is applied between the semiconductor layer and the thin-film metal electrode. An insulator layer made of a material selected from silicon oxide or silicon nitride may be formed between the porous semiconductor layer and the thin-film metal electrode. Si skeletons of the porous semiconductor layer are oxidized or nitrided.

    摘要： An electron emission device based flat panel display apparatus is composed of a pair of a back substrate and an optically transparent front substrate opposing to each other with a vacuum space interposed therebetween, and a plurality of electron emission devices, each of which includes an electron-supply layer made of metal or semiconductor, formed on ohmic electrodes formed on a surface of the back substrate proximate to the vacuum space, an insulator layer formed on the electron-supply layer, and a thin-film metal electrode formed on the insulator layer and facing the vacuum space. The front substrate includes collector electrodes formed on its surface proximate to the vacuum space, fluorescent material layers formed on the collector electrodes, and an image display array composed of a plurality of light emitting elements corresponding to the fluorescent material layers. The electron emission device based flat panel display apparatus also comprises an insulative support member formed on the back substrate and disposed between adjacent ones of the electron emission devices, and a plurality of electrodes, each of which is disposed between adjacent ones of the thin-film metal electrodes and on the insulative support member for electrically connecting the thin-film metal electrodes.
