摘要： An electron emission device includes first and second substrates facing each other with a predetermined distance, cathode electrodes formed on the first substrate, electron emission regions formed on the cathode electrodes, and gate electrodes placed over the cathode electrodes while interposing an insulating layer. The gate electrodes have opening portions exposing the electron emission regions on the first substrate. The electron emission region has a height compensation portion formed on the cathode electrode such that the width of the height compensation portion is reduced in a direction toward the second substrate. An electron emission layer covers the surface of the height compensation portion and contacts the cathode electrode such that the electron emission layer is electrically connected to the cathode electrode.

摘要： An electron emission device includes first and second substrates facing each other, cathode electrodes formed on the first substrate, and electron emission regions formed on the cathode electrodes. Gate electrodes are formed on the cathode electrodes with a first insulating layer interposed between them. A focusing electrode is formed on the first insulating layer and the gate electrodes with a second insulating layer interposed between them. The first insulating layer, the gate electrodes, the second insulating layer and the focusing electrode each have openings exposing the electron emission regions on the first substrate. The size of the opening measured at a surface of the second insulating layer facing the first insulating layer is smaller than the size of the opening measured at a surface of the first insulating layer facing the second insulating layer.
