Abstract:
The purpose of the invention is suppressing a kink phenomenon and improving the image quality of a display device. The display device has a TFT in a pixel. The TFT has a semiconductor layer, a first insulating layer under the semiconductor layer, a second insulating layer over the semiconductor layer, and a gate electrode facing the semiconductor layer with a gap. The gate electrode has a first gate electrode portion facing a lower surface of the semiconductor layer, a second gate electrode portion facing an upper surface of the semiconductor layer, and a third gate electrode portion facing a lateral surface of the semiconductor layer and connected to the first and second gate electrode portions. A laminated part where the first and second insulating layers are stacked is around the semiconductor layer, and a part of the laminated part is between the lateral surface and the third gate electrode portion.
