Abstract
According to one embodiment, a display device includes a substrate unit, a thin film transistor, a pixel electrode and a display layer. The substrate unit includes a substrate, a first insulating layer provided on the substrate, and a second insulating layer provided on the first insulating layer. The thin film transistor is provided on the substrate unit and includes a gate electrode provided on the second insulating layer, a semiconductor layer of an oxide separated from the gate electrode, a gate insulation layer provided between the gate electrode and the semiconductor layer, a first conductive portion, a second conductive portion, and a third insulating layer. The pixel electrode is connected to one selected from the first and second conductive portions. The display layer is configured to have a light emission or a change of optical characteristic occurring according to a charge supplied to the pixel electrode.
