Abstract
In a thin film transistor using a polycrystalline semiconductor film, when a storage capacitor is formed, it is often that a polycrystalline semiconductor film is used also in one electrode of the capacity. In a display device having a storage capacitor and thin film transistor which have a polycrystalline semiconductor film, the storage capacitor exhibits a voltage dependency due to the semiconductor film, and hence a display failure is caused. In the display device of the invention, a metal conductive filmis stacked above a semiconductor layermade of a polycrystalline semiconductor film which is used as a lower electrode of a storage capacitor
