Abstract
An improved flat fluorescent lamp and a display device having the same are disclosed, by which a luminance can be improved and a driving voltage can be reduced. The flat fluorescent lamp may include: a lower substrate; an upper substrate combined with the lower substrate to provide a discharge area; a plurality of walls partitioning the discharge area to provide a plurality of discharge units; first and second voltage-applying electrodes disposed both ends of each discharge unit and exposed to external; first and second discharge electrodes formed on the first and second voltage-applying electrodes, respectively; a dielectric layer coated on the first and second voltage-applying electrodes; and a fluorescent layer formed on the discharge area.
