<p>PROBLEM TO BE SOLVED: To provide an inexpensive and highly efficient electron source substrate for obtaining a flat image forming device with a large screen, capable of keeping an excellent image for a long time. SOLUTION: This electron source substrate has a pair of element electrodes 2, 3 made of a metal formed on a glass base body 1 containing sodium via a sodium diffusion preventing layer and an electron emitting element of a conductive thin film 4 having an electron emitting part 5, and also has metal wirings 6, 7 electrically connected to the electron emitting element and disposed separately from the element electrode and connection wiring 10 electrically connected to the metal wirings 6, 7 and the element electrodes 2, 3.</p> |
