Patent ID: 7905756

Claim:
A method of manufacturing a lower panel of a field emission backlight unit, the method comprising the steps of: forming a conductive material layer on a transparent substrate; patterning the conductive material layer in parallel lines to form alternating first electrodes and second electrodes; forming a plurality of emitter grooves at predetermined intervals along both edges of at least the first electrodes; coating a photoresist material layer on the substrate on which the first electrodes and the second electrodes are formed; patterning the photoresist material layer to expose the emitter grooves; coating a carbon nanotube paste on the photoresist material layer and in the emitter grooves; selectively exposing the carbon nanotube paste to form carbon nanotube emitters in the emitter grooves; and stripping the photoresist material layer and removing unexposed portions of the carbon nanotube paste.
