Abstract: The present disclosure provides a thin film transistor, an electroluminescent display device and a driving transistor. A thin film transistor according to an exemplary embodiment of the present disclosure includes a semiconductor layer, a first insulating layer disposed on the semiconductor layer, two or more first gate electrodes disposed on the first insulating layer and separated from each other, a second insulating layer disposed on the first gate electrodes, a source electrode and a drain electrode disposed on the second insulating layer and respectively electrically connected to a source region and a drain region of the semiconductor layer and a second gate electrode disposed above the first gate electrodes, a channel region may be configured between the source region and the drain region. As a result, it becomes possible to increase subthreshold swing (SS) value, and thus, it becomes possible to improve low gradation spots without increasing a bezel width.
