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.

Abstract: The antifouling film includes a substrate, and a polymer layer disposed on a surface of the substrate and including on a surface thereof an uneven structure provided with multiple projections at a pitch not longer than a wavelength of visible light. The polymer layer is a cured product of a polymerizable composition, the polymerizable composition containing, in terms of active constituents, 15 to 40 wt % of an urethane acrylate containing six or more functional groups, 35 to 60 wt % of a multifunctional acrylate containing four or more functional groups and 3 to 15 ethylene oxide groups for each functional group, 15 to 30 wt % of a monofunctional acrylate with no ethylene oxide group, 0.5 to 10 wt % of a fluorine release agent containing a perfluoropolyether group and having a fluorine atom concentration of 50 wt % or lower, and 0.5 to 5 wt % of a polymerization initiator.
