Abstract
A thin film transistor includes a substrate, a semiconductor layer, a first insulating layer, and a gate electrode. The gate electrode overlaps the semiconductor layer. The thin film transistor includes a second insulating layer on the gate electrode, and an electrode structure on the second insulating layer. The electrode structure is connected to the gate electrode through a via hole. The thin film transistor includes a source electrode and a drain electrode passing through the first insulating layer and the second insulating layer to be connected to the semiconductor layer. The semiconductor layer includes a channel area overlapping the gate electrode, a source area connected to the source electrode, a drain area connected to the drain electrode, a lightly doped source area, and a lightly doped drain area. The electrode structure overlaps at least one of the lightly doped source area or the lightly doped drain area.
