Claim Text:
1. An electron emitting device comprising: a lower electrode; a surface electrode; an electron acceleration layer between the lower electrode and the surface electrode, the electron acceleration layer being made of at least an insulating material; and an electrode selecting unit, wherein at least one of the lower electrode and the surface electrode is a stripe-pattern electrode including a plurality of unit electrodes that are regularly arranged, the electrode selecting unit sequentially selects, from among the plurality of unit electrodes, a unit electrode to which a voltage is to be applied, a voltage is applied between the lower electrode and the surface electrode to accelerate electrons between the lower electrode and the surface electrode, so that the electrons are emitted from the surface electrode, and the electron acceleration layer is made of a resin material containing only conductive microparticles.
