Abstract
Electron emission devices include first electrodes on a substrate extending in a first direction and spaced apart from each other. Second electrodes are on the substrate alternating between the first electrodes and extending in a second direction opposing the first direction. First electron emitters and second electron emitters are on side surfaces of the first electrodes and the second electrodes, respectively. Gaps are formed between the first electron emitters and second electron emitters.
