Electron beam emitting device and image displaying device by use thereof.

摘要

An electron beam emitting device, comprises a surface conduction type of thin film device having an electron emitting area and at least a pair of electrodes for passing current through the electron emitting area, and a voltage applying means for applying independently on each of said electrodes, said voltage applying means being a means for applying voltage on each electrode so that each of the electrodes may become higher or lower in potential relative to the other electrode.
