ABSTRACT:
There is provided an electron-emitting device of a field emission type, with which the spot size of an electron beam is small, an electron emission area is large, highly efficient electron emission is possible with a low voltage, and the manufacturing process is easy. The electron-emitting device includes a layer2which is electrically connected to a cathode electrode5, and a plurality of particles3which contains a material having a resistivity lower than that of a material constituting the layer2, and is wherein a density of particles3in the layer2is 1×1014/cm3or more and 5×1018/cm3or less.
