Abstract:
A display device includes a first wiring functioning as a gate electrode formed over a substrate, a gate insulating film formed over the first wiring, a second wiring and an electrode layer provided over the gate insulating film, and a high-resistance oxide semiconductor layer formed between the second wiring and the electrode layer are included. In the structure, the second wiring is formed using a stack of a low-resistance oxide semiconductor layer and a conductive layer over the low-resistance oxide semiconductor layer, and the electrode layer is formed using a stack of the low-resistance oxide semiconductor layer and the conductive layer which is stacked so that a region functioning as a pixel electrode of the low-resistance oxide semiconductor layer is exposed.
