Electron emission device, electron emission type backlight unit including the same and method of fabricating the electron emission device

An electron emission type backlight unit comprising:

• an electron emission device comprising:
• a base substrate;
• first electrodes extending in a first direction on the base substrate, each first electrode comprising a resistance layer at an end of the first electrode;
• second electrodes electrically insulated from the first electrodes;
• and
• electron emission sources on the first electrodes;
• a phosphor layer facing each of the electron emission sources of the electron emission device;
• and
• a third electrode for accelerating electrons emitted from the electron emission device toward the phosphor layer.

A method of fabricating an electron emission device, the method comprising:

• forming electrodes on a base substrate;
• forming a resistance layer at one end of each of the electrodes;
• performing an aging operation without current flowing through the resistance layer;
• and
• electrically connecting a circuit for driving the electron emission device to the electrodes so that current flows through the resistance layer.
