Abstract
A flat-panel display is fabricated according to a process in which a liquid-containing film (92, 116, 124, 132, 144, or 166) is formed over a substrate (80). In addition to suitable liquid, the liquid-containing film contains oxide or/and hydroxide. Liquid is removed from the liquid-containing film to convert it into a solid porous film (82 or 150) having (a) a porosity of at least 10% along an exposed face of the film, (b) an average resistivity of 108-1014 ohm-cm at 25° C., and (c) an average thickness of no more than 20 &mgr;m. A spacer (24) formed with at least a segment of the substrate and overlying solid porous film is positioned between opposing first and second plate structures (20 and 22) of the display. The second plate structure (22) emits light upon receiving electrons emitted by the first plate structure (20).
