A thin film transistor. The thin film transistor comprises a substrate, a dielectric layer and a polysilicon layer. A gate electrode is located on the substrate. A dielectric layer is located on the substrate and the gate electrode. A polysilicon layer is located on the dielectric layer. The polysilicon layer comprises a channel region and a doped region, wherein the channel region is located above the gate electrode and the doped region is adjacent to the channel region.
