Metal gate electrode and field emission display having same

A field emission display, comprising:

• an anode substrate;
• an anode disposed on a surface of the anode substrate;
• a plurality of spacers;
• a fluorescent layer;
• an insulating substrate;
• and
• a field emission device comprising a fixed element, a dielectric layer, an emitting layer, an cathode and a metal gate electrode, wherein the insulating substrate, the anode substrate, and the plurality of spacers cooperatively define a cavity, the field emission device, the anode, and the fluorescent layer are disposed in the cavity, the fluorescent layer is disposed on a surface of the anode, and the metal gate electrode comprises:
• a plurality of first metal strips arranged substantially along a first direction in parallel;
• and
• a plurality of second metal strips arranged substantially along a second direction in parallel,
• wherein the first direction is substantially perpendicular to the second direction, and the plurality of first metal strips are connected to the plurality of second metal strips to define a plurality of rectangular apertures through which electrons are capable of passing, a first group of the plurality of rectangular apertures are suspended above the electron emitter, and a second group of the plurality of rectangular apertures are sandwiched between the fixed element and the dielectric layer;
• and at least one of the second group of the plurality of rectangular apertures is fully covered by the fixed element and the dielectric layer, wherein a portion of the anode is sandwiched between the anode substrate and the plurality of spacers, and wherein the portion of the anode is in direct with the anode substrate and the plurality of spacers.
