Abstract:
An electron-emitting apparatus, comprising:a substrate; an electron-emitting device comprising a layer structure having: a first electroconductive member provided on a surface of said substrate; an insulation layer provided on said first electroconductive member; and a second electroconductive member provided on said insulation layer; an anode electrode provided apart from the surface of said substrate; first voltage application means for applying potential, higher than potential applied to said first electroconductive member, to said second electroconductive member; and second voltage application means for applying potential, higher than potential applied to said second electroconductive member, to said anode electrode, wherein T1<AÃ—exp [BÃ—(Vfâˆ’&phgr;wk)/(Vf)]A=âˆ’0.50+0.56Ã—log (T3), B=8.7 where: on an end plane of said insulation layer placed substantially parallel to the surface of said substrate, an end portion of said first electroconductive member and an end portion of said second electroconductive member are set opposite each other with a space between; in a direction of the end portion of said first electroconductive member and the end portion of said second electroconductive member set opposite each other, said second electroconductive member is T1 [nm] long; said first electroconductive member extending from a surface of said first electroconductive member substantially parallel to the surface of said substrate toward the direction in which the end portion of said first electroconductive member and the end portion of said second electroconductive member are set opposite each other is T3 [nm] long; a work function of said second electroconductive member is &phgr;wk [eV]; a voltage applied between said first electroconductive member and said second electroconductive member is Vf [V].
