Abstract
In order to cause a multi-electron source having electron emitters wired in the form of a matrix to emit electrons without any variations, there is provided an electron generating device including 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 the multi-electron source ( ), the driving circuit including a first driving means ( ) for applying a first voltage (Vs) to a scanning wiring layer to which an electron emitter which is to emit electrons is connected, and applying a second voltage (Vns) to a scanning wiring layer to which an electron emitter which is not to emit electrons is connected, and a second driving means ( ) for applying a third voltage (Ve) to a data wiring layer to which an electron emitter which is to emit electrons is connected, and applying a fourth voltage (Vg) to a data wiring layer to which an electron emitter which is not to emit electrons is connected, wherein the second voltage (Vns) is substantially equal to the third voltage (Ve).
