Abstract
A display device having a gate driver which may reduce generation of ripple at the output of the gate drive includes: a substrate; and a driver circuit including a thin film transistor disposed on the substrate, the thin film transistor including: a first gate electrode disposed on the substrate; a semiconductor layer disposed on the first gate electrode to overlap a part of the first gate electrode, the semiconductor layer including channel, source, and drain regions; a second gate electrode disposed on the semiconductor layer; and a source electrode and a drain electrode disposed on the semiconductor layer and respectively connected to the source region and the drain region, wherein a first area formed by the overlapping portion of the first gate electrode and the drain region has a different size than a second area formed by the overlapping portion of the first gate electrode and the source region.
