Method of manufacturing electron emission device, electron emission device manufactured using the method, and backlight unit and electron emission display device employing electron emission device

An electron emission type backlight unit, comprising:

• an upper substrate and a lower substrate disposed in parallel at a predetermined interval;
• an anode electrode formed on the upper substrate;
• a phosphor layer formed on the anode electrode to a predetermined thickness;
• and
• an electron emission device interposed between the upper substrate and the lower substrate;
• wherein the electron emission device comprises a cathode electrode formed on a substrate, an emitter formed by patterning on the cathode electrode, a photosensitive glass paste layer burying the emitter, and a gate insulating layer formed by patterning the photosensitive glass paste layer.
