Abstract:
1. An electron-emitting device comprising at least: a pair of device electrodes formed on a substrate; and an electroconductive film formed on the substrate so as to connect the device electrodes, wherein the electroconductive film has a first gap between the device electrodes and has a carbon film having a second gap at least in the first gap, the substrate is constructed by stacking a base, an activation suppressing layer containing nitrogen, and an activation accelerating layer whose nitrogen containing ratio is smaller than that of the activation suppressing layer, in order, the pair of device electrodes and the electroconductive film are disposed on the activation accelerating layer, the substrate has distribution of the nitrogen containing ratio in the activation suppressing layer in a film thickness direction, and the nitrogen containing ratio of the activation suppressing layer at the activation accelerating layer side is smaller than that at the base side.
