Abstract:
1. A cathode plate of a field emission display, comprising: a substrate; a patterned mask layer or absorption layer, disposed on a surface of the substrate; a patterned electrode layer, covering sidewalls and a top surface of the mask layer and a portion of the substrate around the mask layer; a plurality of emitters, respectively disposed on the patterned electrode layer, wherein the entire sidewall surface of each emitter is exposed; a dielectric layer, covering a top surface of the patterned electrode layer and the substrate, wherein the dielectric layer has via holes corresponding to the patterned mask layer and exposing the emitters; and a patterned gate layer, disposed on the dielectric layer, wherein the patterned gate layer has gate holes corresponding to the via holes and exposing the emitters.
