发明名称 Semiconductor device
摘要 To realize a semiconductor device including a capacitor element capable of obtaining a sufficient capacitor without reducing an opening ratio, in which a pixel electrode is flattened in order to control a defect in orientation of liquid crystal. A semiconductor device of the present invention includes a light-shielding film formed on the thin film transistor, a capacitor insulating film formed on the light-shielding film, a conductive layer formed on the capacitor insulating film, and a pixel electrode that is formed so as to be electrically connected to the conductive layer, in which a storage capacitor element comprises the light-shielding film, the capacitor insulating film, and the conductive layer, whereby an area of a region serving as the capacitor element can be increased.
