ABSTRACT:
A triode type field emission display in accordance with the invention includes: a cathode electrode (12) formed on an insulation substrate (10); an insulation layer (13) formed on the cathode electrode; a gate electrode (14) formed on the insulation layer; a number of emitters (16); and an anode electrode (18) with a phosphor layer (19) positioned over the gate electrode. The emitters are distributed on portions of the cathode electrode at two sides of the insulation layer, and a height of the emitters is less than a thickness of the insulation layer. The emitters are capable of emitting electrons from tips thereof, and the emitted electrons are focused on the phosphor layer by an electric field generated by the gate electrode.
