    摘要： In a field emission device, the fundamental cause of spherical aberration in an emitted electron beam trajectory is eliminated or mitigated. An aberration suppressor electrode 31 is provided at a lower vertical position than an extraction gate electrode 13 so its opening inner peripheral edge 31e faces a position near an emitter tip 11tp. The vertical position of the opening inner peripheral edge 31e of the aberration suppressor electrode 31 is made lower than the vertical position of the emitter tip 11tp. An aberration suppressing voltage Vsp is applied to the aberration suppressor electrode 31 that is a lower voltage than the potential of the emitter 11 and controls equipotential lines near the emitter tip 11tp to make them parallel.

    摘要： An image display device is provided in which the overall brightness of an image can be varied without adversely affecting hue and contrast. The image display device includes emitters 16 connected to a cathode electrode 15, a gate electrode 13, an anode electrode 3, transistors Tr1 and Tr2, and a capacitor 12. A voltage applied to the capacitor 12 is varied to display an image. A constant voltage is applied to the gate electrode 13 to change a time ratio Du. Thus, the overall brightness of an image can be adjusted.

    摘要： A stable field-emission electron source that does not suffer from a current drop even after a high-current density operation for a long time is provided. The field-emission electron source includes: a substrate; an insulating layer that is formed on the substrate and that has a plurality of openings; cathodes arranged at the respective openings in order to emit electron beams; a lead electrode formed on the insulating layer in order to control emission of electrons from the respective cathodes; and a surface-modifying layer formed on the surface of each of the cathodes emitting electrons, comprising a chemical bond between a cathode material composing the cathodes and a material different from the cathode material.
