Abstract
A method for manufacturing a cathode assembly of a field emission display, includes the steps of: providing a substrate () with a cathode () formed thereon; forming an electrically insulating layer (), a gate electrode layer () and a photoresist layer () on a cathode in series; defining at least one opening () in the photoresist layer using a photolithographic process; etching the gate electrode layer through the at least one opening so as to form at least one gate electrode opening () in the gate electrode layer; etching the electrically insulating layer to define at least one cavity () in the electrically insulating layer; pressing the photoresist layer in a manner such that a size of the at least one opening is reduced; depositing a catalyst layer () in the at least one cavity through the at least one opening; and growing carbon nanotubes () on the catalyst layer.
