Solution for fabrication of electron-emitting devices, manufacture method of electron-emitting devices, and manufacture method of image-forming apparatus

A manufacture method of electron-emitting devices each provided between electrodes with a conductive film including an electron-emitting region, said electron-emitting devices being capable of emitting electrons from the electron-emitting region to the outside thereof, wherein the method comprises:

• (a) a process of forming creating the conductive film in which the electron-emitting region is to be formed that includes a step of coating and calcining a solution which contains 0.1 wt % to 10 wt % of a metal carboxylate expressed by the following general formula (I), an organic solvent and/or , and water;
• (R(COO)k)mM (I)
• where k=numeral from 1 to 4 , m=a numeral from 1 to 4, and R=CnX2n+1−k X2n+2−k where X=a hydrogen or halogen (total number of hydrogen and halogen atoms is 2n+1) , n=an integer from 0 to 30, and M=a metal, wherein said organic solvent is a carboxylic ester having the same carboxylic group as R(COO)k expressed in the general formula (I), at least 90% of the metal carboxylate being decomposed during the calcining step;
• and
• (b) a process of forming the electron-emitting region in said created conductive film.
