ABSTRACT:
An electron-emitting device comprises a pair of opposing electrodes formed on a substrate, an electroconductive film having a fissure arranged between the pair of electrodes, and at least a film having a gap and containing carbon as a main ingredient, arranged at an end portion of the electroconductive film facing the fissure.The fissure is a region of 95% or more of a length in the fissure direction, has a width of from 60 nm or more to 800 nm or less, and has a difference of 300 nm or less between a maximum value and a minimum value of the width, thereby providing high withstanding voltage without forming branched fissure.
