| 1. A flat fluorescent lamp for flat panel display backlighting, comprising:
a main plate having at least one through-hole formed to penetrate the main plate, the at least one through-hole being extended
from one side surface of the main plate to the other side surface of the main plate;
electrode units attached to respective sides of the main plate, each of the electrode units having at least one electrode
corresponding to the at least one through-hole of the main plate, the electrode units sealing respective ends of the at least
one through-hole of the main plate;
a fluorescent material applied to an inner circumferential surface of the at least one through-hole of the main plate; and
a light-emitting gas filled in an inner space defined by the at least one through-hole of the main plate and the electrode
units, wherein each of the electrode units has at least one depression part in which the at least one electrode is disposed,
a diameter of the at least one depression part being greater than a diameter of the at least one through-hole of the main
plate.
