Abstract: A thin film transistor includes an oxide semiconductor layer having a polycrystalline structure over a substrate, a gate electrode over the oxide semiconductor layer, and a gate insulating layer between the oxide semiconductor layer and the gate electrode. The oxide semiconductor layer includes a first region having a first carrier concentration and overlapping the gate electrode, a second region having a second carrier concentration and not overlapping the gate electrode, and a third region between the first region and the second region and overlapping the gate electrode. The second carrier concentration is larger than the first carrier concentration. A carrier concentration of the third region decreases from the second region to the first region in a channel length direction. A length of the third region is greater than or equal to 0.00 μm and less than or equal to 0.60 μm in the channel length direction.
