Abstract: A flat fluorescent lamp includes a lamp body and first external electrodes. The lamp body has discharge spaces formed therein. The first external electrodes are disposed at a first end portion of an outer surface of the lamp body and a second end portion that is opposite to the first end portion to define a first region where the discharge spaces overlap the first external electrodes and a second region where the discharge spaces do not overlap the first external electrodes. Each of the discharge spaces has a first width at the first region and a second width that is smaller than the first width at the second region. Therefore, an overlapping region between the first external electrodes and the discharge space increases to lower the discharge voltage.
