ABSTRACT:
A field emission light source includes a substrate, a cathode conductive layer, a plurality of electron emitters, a transparent substrate, an anode layer and a fluorescent layer. The cathode conductive layer is formed on the substrate. The electron emitters are disposed on the cathode conductive layer. The transparent substrate is spaced from the cathode conductive layer. The anode layer is formed on the transparent substrate facing the electron emitters and includes a carbon nanotube film structure having carbon nanotubes arranged in a preferred orientation. The fluorescent layer is formed on the anode layer facing the electron emitters.
