Title: Display device and method for manufacturing the same

Abstract: A display device having the high aperture ratio and a storage capacitor with high capacitance is to be obtained. The present invention relates to a display device and a manufacturing method thereof. The display device includes a thin film transistor which includes a gate electrode, a gate insulating film, a first semiconductor layer, a channel protective film, a second semiconductor having conductivity which is divided into a source region and a drain region, and a source electrode and a drain electrode; a third insulating layer formed over the second conductive film; a pixel electrode formed over the third insulating layer, which is connected to one of the source electrode and the drain electrode; and a storage capacitor formed in a region where a capacitor wiring over the first insulating layer and the pixel electrode are overlapped with the third insulating layer over the capacitor wiring interposed therebetween.
