Abstract
A fabrication method for an emitter includes the steps of forming on a glass substrate a CNT film which contains a plurality of carbon nanotubes (CNTs) and constitutes an emitter electrode, forming a gate electrode via an insulating film on the CNT film, forming a plurality of gate openings in the gate electrode and the insulating film, and aligning upright the CNTs in the gate opening. The upright alignment generates a stable uniform emission current and provides excellent emission characteristics.
