Abstract: An electric field emission display (FED) and a method for manufacturing a spacer thereof are provided. The FED includes a spacer having a structure in which a multi-focusing electrode layer, an electron beam amplifying layer and a getter layer are stacked between an anode and a cathode, or a spacer having a structure in which a first electrode layer, a first insulating layer, a second electrode layer, a second insulating layer, a third electrode layer, a third insulating layer and a fourth electrode layer are sequentially stacked. Thus, electron beams can be easily focused by the multi-focusing electrode of the spacer, and high luminance can be realized at low current due to electron beam amplification of the electron amplifying apparatus. Also, the diamond tip is used as an electron emission means, to thereby obtain a low driving voltage, stability at a high temperature, and high thermal conductivity. Also, a getter formed of a thin film is used, to thereby minimize a getter adhesion space, and an insulating layer formed of ceramic is used, to thereby suppress leakage current of the electrodes. According to the method for manufacturing the FED and a spacer thereof, time for manufacturing the spacer is reduced, and support stiffness is increased by the insulating layers formed of ceramic interposed between the electrode layers, to thereby increase the aspect ratio of the spacer to a desired level. Also, a multitude of electrode layers to which the negative voltage is applied, is provided in the spacer, to thereby suppress absorption of electrons to the surface of the spacer, and the number of electrons colliding against the fluorescent material is increased, to thereby increase the luminance of the device.

Abstract: The invention relates to a display device having under-gate emitters, i.e. emitters where the gates (203) are arranged under the cathodes (205), beneath an insulating layer (204). In order to protect the emitters from a high electric field from an anode (A), an electron guidance element (207) is placed between the emitters and the anode. This allows a relatively low voltage swing to be used for controlling the electron emission from the emitters from the on-state to the off-state.
