Abstract:
A method for manufacturing a field emission cathode, comprising the steps of:forming a cathode electrode pattern on a cathode substrate; forming a photoresist layer; superposing an intaglio provided with recesses for formation of projections and coated thereon with a release agent on the photoresist layer; subjecting the photoresist layer to molding under a pressure while being heated, to thereby form the photoresist layer with the projections and modify the photoresist layer; peeling off the intaglio; subjecting a surface of the modified photoresist layer to etching; forming an insulating layer on the modified photoresist layer; forming a gate electrode pattern on the insulating layer; and subjecting a lamination between lead-out electrodes on the gate electrode pattern and the insulating layer, to thereby form the lamination with openings; the projections of the photoresist layer each being exposed at a distal end thereof from a portion of the insulating layer positioned at each of the openings.
