<p>PROBLEM TO BE SOLVED: To provide an electron emission element that is easy in making the size large area as well as improved in electron emission property by using a glass substrate that does not require treatment such as coating on the glass substrate. SOLUTION: This is an electron emission element that has carbon membranes 12, 13 opposed to each other interposing a first gap part 11 that are arranged on the glass substrate 1 or carbon membranes having a first gap part on part of it, and the first gap part 11 and/or glass substrate 1 contains at least each element of silicon, aluminum, boron, alkaline earth metal, carbon and oxygen.</p> |
