ABSTRACT:
In a flat panel display using a field emission type cathode array, a flat fluorescent screen is arranged between a cathode array formed on a flat substrate and a screen comprising a glass plate having a convex curved shape in parallel with the substrate. The space between the fluorescent screen and the cathode array and the space between the fluorescent screen and the substrate has a vacuum thereon. In a method of manufacturing the display, a plurality of cathodes are formed on a conductive substrate, after the plurality of cathodes were formed, a field evaporation is caused from tips of the plurality of cathodes by applying a predetermined voltage to the plurality of cathodes.
