A Reflective Field Emission Display (FED) pixel element and system employing same are disclosed. In the FED system disclosed, each pixel element is composed of at least one emitter that is operable to emit electrons and at least one reflector that is operable to attract and reflect the emitted electrons onto a transparent anode layer that oppositely positioned with respect to the emitter and reflector and is operable to attract the reflected electrons. In one aspect of the invention, the emitter layer is shaped to bound the reflector layer forming an electrical boundary that focuses the reflected electron beam onto a phosphor layer interposed between the transparent layer. In another aspect of the invention, a high voltage and a corresponding high voltage phosphor is applied to the transparent anode layer. The use of high voltage and high voltage phosphor is advantageous as it causes the reflected electrons to be drawn deeper into the phosphor layer and, hence, reduces unwanted emissions back into the vacuum of the pixel element. In still another aspect of the invention, a plurality of phosphor layers are applied to the transparent layer to produce a color display as reflected electrons are attracted to the transparent layer.
