Patent ID: 10643815

Abstract:
Provided are an electron emission device having a novel structure and being capable of improving characteristics and/or extending a lifetime of a related-art electron emission device, and a method of manufacturing the electron emission device. The method of manufacturing an electron emission device includes: a step A of providing one of an aluminum substrate and an aluminum layer supported by a substrate; a step B of anodizing a surface of the one of the aluminum, substrate and the aluminum layer to form a porous alumina layer having a plurality of pores; a step C of applying silver nanoparticles into the plurality of pores to cause the plurality of pores to support the silver nanoparticles; a step D of applying, after the step C, an insulating layer forming solution to substantially an entire surface of the one of the aluminum substrate and the aluminum layer; a step E of forming, after the step D, an insulating layer by at least reducing a solvent included in the insulating layer forming solution; and a step F of forming an electrode on the insulating layer.
