Abstract
A field-emission structure suitable for large-area flat-panel televisions centers around an insulating porous layer that overlies a lower conductive region situated over insulating material of a supporting substrate. Electron-emissive filaments occupy pores extending through the porous layer. A conductive gate layer through which openings extend at locations centered on the filaments typically overlies the porous layer. Cavities are usually provided in the porous layer along its upper surface at locations likewise centered on the filaments.
