Abstract:
1. A method for manufacturing a field emission display (FED), the method comprising the steps of: (a) preparing a back plate on which a cathode, a first electron emission source and a gate electrode for controlling an electron emission on the cathode are formed, in a predetermined active display region; (b) preparing a front plate on which an anode corresponding to the cathode and a phosphor layer from which light is emitted by electrons emitted from the first electron emission source are formed; (c) forming a supporter on an inner surface of the front plate or the back plate; (d) forming a getter anode and a getter layer on the supporter; (e) forming a getter cathode on an inner surface of the back plate or the front plate to face the getter anode; (f) forming a second electron emission source on the getter cathode; (g) sealing the edges between the front plate and the back plate, exhausting gas and evacuating a space between the front plate and the back plate; and (h) activating the getter layer by applying voltage to the getter anode and the getter cathode so that gases generated in the space is absorbed.
