CATHODE FOR FIELD EMISSION DISPLAY

摘要

PURPOSE: A cathode for a field emission display is provided to distribute uniformly the electric field to an emitter by forming a catalytic layer at a side portion of a gate hole and growing the emitter on the catalytic layer. CONSTITUTION: A cathode for a field emission display includes a substrate(200), a catalytic layer(230), a dielectric layer(240), a gate electrode(250), an emitter(280), and a gate hole(270). The catalytic layer, the dielectric layer, the gate electrode, and the emitter are stacked on the substrate. The substrate is exposed by the gate hole. The gate electrode and the catalytic layer are formed at both sides of the gate hole, respectively. The gate electrode and the catalytic layer are located at positions of different height, respectively. A buffer layer is formed on an exposed surface of the gate electrode.
