Abstract
An electron emitting device includes at least an electron transporting member ( ), an electron emitting member ( ), and an electric field concentration region ( ) formed between the electron transporting member ( ) and the electron emitting member ( ). For example, the electron transporting member ( ) may be a conductive layer, the electric field concentration region ( ) may be formed of an insulating layer formed on the conductive layer, and the electron emitting member ( ) may be formed of particles provided on the insulating layer. Due to the electric field concentration in the electric field concentration region ( ), electrons are easily injected from the electron transporting member ( ) to the electron emitting member ( ).
