Abstract
Disclosed is an ultraviolet light-emitting element which uses an electron emission operation. The ultraviolet light-emitting element is sealed to maintain a high degree of vacuum. A emission substrate is prepared for the electron emission and an electron emitted from the emission substrate passes through a control substrate. The electron, which has passed through the control substrate, collides with a light-emitting substrate, from which formation of a p-type semiconductor has been excluded, and thus forms ultraviolet light.
