ABSTRACT:
A method of fabricating a field emission display employing carbon nanotubes (CNTs) as electron emitters is provided. The method includes forming a cathode on a substrate; forming a gate insulation layer having a plurality of gate holes on the cathode; forming a gate electrode having a plurality of via-holes corresponding to the gate holes, respectively, on the gate insulation layer; forming a plurality of conductive columns higher than the gate electrode on the cathode within the respective gate holes; adhering the CNTs to the bottom of a plate template which is separately provided; bringing the bottom of the template having the CNTs to contact the tops of the conductive columns to adhere the CNTs to the tops of the conductive columns; and firing the conductive columns to lower the levels thereof. Accordingly, the problems of conventional methods, such as sinking of CNTs caused by screen printing, residual CNTs remaining within a gate when a lift-off method is used and short circuiting between gate and cathode due to the residual CNTs, can be solved. In addition, CNTs are applied to only a part for field emission, that is, only the top of a conductive column, thereby requiring fewer CNTs and decreasing fabrication cost. Moreover, the method uses stamping in order to form CNTs, so it is very advantageous in mass production.
