ABSTRACT:
Boron nitride nanotube paste compositions, electron emission sources including the same, electron emission devices including the same and backlight units and electron emission display devices including the same are provided. A boron nitride nanotube paste composition includes about 100 parts by weight boron nitride nanotubes, from about 500 to about 2000 parts by weight glass frit, from about 1000 to about 2000 parts by weight filler, from about 2000 to about 4000 parts by weight organic solvent, and from about 4000 to about 6000 parts by weight polymer binder. Electron emission devices including the boron nitride nanotube electron emission sources have longer lifespan and improved uniformity among pixels.
