Document Type and Number:
Japanese Patent JP6655136
Kind Code:
B2
Abstract:
To provide an electron emission element that can adjust an amount of electron to be partially emitted and suppress charging unevenness.SOLUTION: An electron emission element 20 applies voltage to a position between a first electrode and a second electrode 40 arranged opposite to each other to emit electron from the second electrode 40. The electron emission element 20 comprises: an electron acceleration layer 50 that is provided between the first electrode and the second electrode 40 and accelerates electron directed from the first electrode to the second electrode 40; and a plurality of voltage application parts DH. The plurality of voltage application parts DH are connected respectively to first power sources 8a corresponding thereto and individually drives.SELECTED DRAWING: Figure 3A
