Abstract:
1. An electron-emitting device comprising: 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, wherein the fissure is a region of 95% or more of a length in a fissure direction, and has a width of from 60 nm or more to 800 nm or less, and there is a difference of 300 nm or less between a maximum value and a minimum value of the width, and wherein the electroconductive film has a film thickness of 12 nm or less in a region of 80% or more of a length of the electroconductive film in the fissure direction except for both end portions thereof, and there is a difference of 4 nm or less between a maximum value and a minimum value of the film thickness.
