Abstract:
An electron generating device comprising a multi-electron source having a plurality of electron emitters wired in the form of a matrix through a plurality of data wiring layers and a plurality of scanning wiring layers, and a driving circuit for driving said multi-electron source, said driving circuit including:first driving means for applying a first voltage to a scanning wiring layer to which an electron emitter which is to emit electrons is connected, and applying a second voltage to a remaining scanning wiring layer of the plurality of scanning wiring layers to which an electron emitter which is not to emit electrons is connected; and second driving means for selectively applying one of a third voltage and a fourth voltage, wherein the third voltage is applied to a data wiring layer to which an electron emitter which is to emit electrons is connected and the fourth voltage is applied to a data wiring layer to which an electron emitter which is not to emit electrons is connected, wherein the second voltage is substantially equal to the third voltage.
