Abstract
A flat-panel display is fabricated according to a process in which a liquid-containing film ( , or ) is formed over a substrate ( ). 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 ( or ) having (a) a porosity of at least 10% along an exposed face of the film, (b) an average resistivity of 10 ohm-cm at 25° C., and (c) an average thickness of no more than 20 &mgr;m. A spacer ( ) formed with at least a segment of the substrate and overlying solid porous film is positioned between opposing first and second plate structures ( and ) of the display. The second plate structure ( ) emits light upon receiving electrons emitted by the first plate structure ( ).
