ABSTRACT:
An electron emission device, and an electron emission display using the electron emission device, includes a substrate, electron emission regions formed on the substrate, driving electrodes formed on the substrate to control electron emissions of the electron emission regions, and a focusing electrode disposed above the driving electrodes and insulated from the driving electrodes, the focusing electrode having openings through which electron beams pass. The focusing electrode includes at least two focusing parts electrically separated from each other and the focusing parts focus the electron beams in different directions.
