Flat panel display having field emission cathode and manufacturing method thereof

Abstract

Disclosed is a flat panel display and a method for manufacturing the same. The flat display has a first substrate and a second substrate sealed in a vacuum at a predetermined interval to form a cell gap and including a plurality of spacers interposed therebetween, the second substrate including a plurality of anode electrodes formed in a predetermined pattern on one side thereof and a phosphor layer formed on the pattern of the anode electrodes. The flat panel display further includes a plurality of cathode electrodes formed in a predetermined pattern on the first substrate; an insulating layer disposed on the cathode electrodes and having a plurality of apertures formed therein; a plurality of field emission cathodes provided in the apertures of the insulating layer contacting the cathode electrodes; a gate electrode pattern realized through a plurality of gate electrodes, the gate electrode pattern being disposed on the insulating layer and having formed openings corresponding, in size and location, to the apertures of the insulating layer; and a plurality of focusing electrodes provided between the gate electrode pattern and the cathode electrodes, and which control the flow of electrons emitted from the same.
