Abstract:
1. A method of manufacturing a field emission display, the method comprising: (a) forming a transparent cathode layer on a transparent substrate; (b) forming a first insulating layer on the substrate and the cathode layer; (c) forming a first gate layer having a first gate hole on the first insulating layer; (d) forming a second insulating layer on the first insulating layer and the first gate layer; (e) forming a second gate layer having a second gate hole having a diameter smaller than that of the first gate hole on the second insulating layer; (f) etching the second insulating layer exposed through the second gate hole and the first insulating layer under the second insulating layer and forming a cavity through which part of the cathode layer is exposed and none of the first gate layer is exposed; (g) patterning the second gate layer as a predetermined shape; and (h) forming a field emitter on the cathode layer exposed to the bottom of the cavity.
