Abstract

It is an object to provide a semiconductor device with less power consumption as a semiconductor device including a thin film transistor using an oxide semiconductor layer. It is an object to provide a semiconductor device with high reliability as a semiconductor device including a thin film transistor using an oxide semiconductor layer. In the semiconductor device, a gate electrode layer (a gate wiring layer) intersects with a wiring layer which is electrically connected to a source electrode layer or a drain electrode layer with an insulating layer which covers the oxide semiconductor layer of the thin film transistor and a gate insulating layer interposed therebetween. Accordingly, the parasitic capacitance formed by a stacked-layer structure of the gate electrode layer, the gate insulating layer, and the source or drain electrode layer can be reduced, so that low power consumption of the semiconductor device can be realized.
