Abstract: A thin film transistor for a display device can include an active layer disposed on a substrate, a gate electrode overlapping with the active layer, a source electrode electrically connected to the active layer, a drain electrode electrically connected to the active layer, and at least one hole in the active layer, in which the at least one hole at least partially overlaps with an edge of the gate electrode. Also, the at least one hole in the active layer can control or block diffusion of a dopant within the active layer.

Abstract: A gate driver and a display device including the same are disclosed. The gate driver includes a plurality of stages. Each stage includes a first transistor outputting a first clock signal as a scan signal in accordance with a first node, a second transistor outputting a gate-off voltage as the scan signal in accordance with a second node which is activated as opposed to the first node, a first controller activating the first node to a gate-on voltage in response to a start signal or a carry signal and a fourth clock signal, and a second controller activating the second node to the gate-on voltage in response to a second clock signal and a third clock signal.
