PROBLEM TO BE SOLVED: To attain a thin film type electron source in which gas adsorption, in particular, adsorption of sulfur component is little, and attain an image display device with a long life. SOLUTION: This is structured so that the surface of the upper electrode 13 of the thin film type electron source is covered by an oxide 19, and so that the sulfur component generated from a fluorescent material by electron beam irradiation will not be adsorbed to the upper electrode 13. Thereby, reduction of an electron emission efficiency can be prevented, and the image display device which is provided with the thin film type electron source and superior in reliability can be attained.
