ABSTRACT:
A field emission display and a method therefor, which can substantially improve uniformity of electrons emitted from numerous micro-tips formed to be applied to a flat panel display, by etching the edges of cathodes which are shaped into stripes and forming resistance portions in the etched areas, thereby improving an excessive etching and roughness made in etching a hole in an area for forming a micro-tip. Thus, the display is free of the decrease in tip-adhesion, so that the process efficiency can be increased up to 90% and the uniformity difference between the electrons emitted from a plurality of micro-tips can be maintained at .+-.5% in the edge and center of the cathode.
