Patent ID: 7459843

Claim:
An electron emission device comprising: first and second substrates facing each other with a distance therebetween; an electron emission region on the first substrate; a first electrode and a second electrode on the first substrate while being insulated from each other to control an electron emission of the electron emission region; an insulating layer between the first and second electrodes; an anode electrode on the second substrate; and a phosphor layer on a surface of the anode electrode; wherein the insulating layer has a multiple-layered structure comprising a first layer having a first specific resistance higher than a second specific resistance and a second layer having the second specific resistance, the first layer physically contacting one of the first electrode or the second electrode, the second layer physically contacting the other one of the first electrode or the second electrode, and wherein the second layer has a specific resistance from 10 5 to 10 12 Ωcm.
