Abstract
An object is to provide a liquid crystal display device in which a pixel including a thin film transistor using an oxide semiconductor has a high aperture ratio. The liquid crystal display device includes a plurality of pixels each including a thin film transistor and a pixel electrode. The pixel is electrically connected to a first wiring functioning as a scan line. The thin film transistor includes an oxide semiconductor layer over the first wiring with a gate insulating film therebetween. The oxide semiconductor layer is extended beyond the edge of a region where the first wiring is provided. The pixel electrode and the oxide semiconductor layer overlap with each other.
