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 manufa…
