Electron emission device and electron emission display device

An electron emission display device comprising:

• a first substrate;
• a second substrate facing the first substrate;
• an electron emission region formed on the first substrate for emitting electrons;
• a driving electrode for controlling the emission of the electrons from the electron emission region, the driving electrode comprising an effective portion for inducing the emission of the electrons from the electron emission region, and a first voltage applying portion electrically connected to the effective portion;
• a focusing electrode electrically insulated from the driving electrode, the focusing electrode comprising a focusing portion for focusing the electrons emitted from the electron emission region and a second voltage applying portion electrically connected to the focusing portion;
• a phosphor layer formed on the second substrate;
• and
• an anode electrode formed on a surface of the phosphor layer,
• wherein the effective portion and the focusing portions are disposed in different planes from each other, and the first voltage applying portion and the second voltage applying portion are non-overlapping.
