ABSTRACT:
An electron emission device includes first and second substrates facing each other with a predetermined distance therebetween, and an electron emission region formed on the first substrate. First and second electrodes are placed on the first substrate while being insulated from each other to control an electron emission of the electron emission region. An insulating layer is disposed between the first and second electrodes. An anode electrode is formed on the second substrate. A phosphor layer is formed on a surface of the anode electrode. The insulating layer has a multiple-layered structure including at least two layers differing from each other in electro-physical property.
