Abstract
To provide a liquid crystal display device having high quality display with a high aperture ratio while securing a sufficient storage capacitor (Cs), and at the same time, by dispersing a load (a pixel writing-in electric current) of a capacitor wiring in a timely manner to effectively reduce the load. A scanning line is formed on a layer that is different from a gate electrode so that the capacitor wiring is arranged in parallel with a signal line. Each pixel is connected to the individually independent capacitor wiring via a dielectric. Therefore, variations in the electric potential of the capacitor wiring caused by a writing-in electric current of adjacent pixels can be avoided, thereby obtaining satisfactory display images.
