Abstract:
An electron emission source is provided. The electron emission source includes a first electrode, an insulating layer, and a second electrode. The first electrode, the insulating layer, and the second electrode are successively stacked with each other. the second electrode is a graphene layer, and the graphene layer is an electron emission end to emit electron. A thickness of the graphene layer ranges from about 0.1 nanometers to about 50 nanometers.
