Boron nitride nanotube paste composition, electron emission source including the same, electron emission device including the electron emission source, and backlight unit and electron emission display device including the electron emission device

摘要

A boron nitride nanotube paste composition, an electron emission source including the same, an electron emission device including the same and a backlight unit and an electron emission display device including the same are provided. The boron nitride nanotube paste composition includes about 100 parts by weight boron nitride nanotubes, from about 250 to about 1000 parts by weight glass frit, from about 500 to about 1000 parts by weight filler, from about 1000 to about 2000 parts by weight organic solvent, and from about 2000 to about 3000 parts by weight polymer binder. Electron emission devices including the boron nitride nanotube electron emission sources have longer lifespan and improved uniformity among pixels.
