ABSTRACT:
A planar light source device includes a lower substrate, a cathode electrode a carbon nanotube, an upper substrate, a fluorescent layer, and an anode electrode. The cathode electrode is on the lower substrate. The carbon nanotube is electrically connected to the cathode electrode. The upper substrate faces the lower substrate. The fluorescent layer and the anode electrode are formed on the upper substrate. Therefore, the planar light source device generates light without using mercury.
