Electron-emitting device, electron source substrate, electron beam apparatus, display apparatus, and manufacturing method thereof

A method of manufacturing an electron-emitting device comprising:

• a pair of facing 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 method comprising:
• at least a liquid drop applying process for liquid drop-applying electroconductive film ingredient-containing liquid containing the ingredient of the electroconductive film,
• wherein in the liquid drop applying process, the liquid drop-applying is conducted a plurality of times for one portion one after another, and wherein at every interval between respective performances of the liquid drop-applying, 96 wt % to 99 wt % based on 100 wt % of a solvent contained in a liquid drop is evaporated.
