Electron source and image display device

摘要

An electron source includes a substrate, a coating layer provided on the substrate, plural electron emission elements disposed on the coating layer, and a metal for connecting the plural electron emission elements. The electron emission element includes a conductive film including the electron emission part disposed on the coating layer, with the conductive film being connected to a wiring line with a conductive member for blocking the metals contained in the wiring lines from being transferred to the conductive film.
