Abstract
According to one embodiment, a semiconductor device includes an insulating substrate, a polycrystalline silicon semiconductor, an oxide semiconductor, a gate electrode located directly above the oxide semiconductor, a first conductive layer in contact with the polycrystalline silicon semiconductor via a first contact hole, and in contact with the oxide semiconductor via a second contact hole and a second conductive layer stacked on the first conductive layer between the first contact hole and the second contact hole. The first conductive layer includes an extending portion extending from the second contact hole toward the gate electrode. The second conductive layer is not stacked on the extending portion. The first conductive layer is thinner than the second conductive layer.
