Abstract:
1. A field emission display having a gate plate, comprising: an anode plate having a transparent electrode on a substrate and a phosphor on a portion of the transparent electrode; a cathode plate having row/column signal lines of a belt shape for which row/colunm addressing is possible on the substrate, and pixels each defined by the row signal line and the colunm signal line, wherein each pixel has a film-shape field emitter and a control device for controlling the field emitter, having two terminals connected to at least the row/column signal lines and one terminal connected to the film-shape field emitter; a gate plate fabricated separately from the cathode plate, wherein each pixel of the gate plate has at least one gate hole penetrating therein and a gate electrode surrounding the top of the gate hole; and spacers for supporting the gate plate between the cathode plate and the anode plate, one end of the spacers is in contact with one of the anode plate and the cathode plate, and another end of the spacers is in contact with the gate plate, wherein the field emitter of the cathode plate is constructed to be opposite to the phosphor of the anode plate through the gate holes and is formed by vacuum packaging, wherein each gate hole is an aperture for its enclosed pixel, and the gate plate and the cathode plate are assembled together after being fabricated separately.
