The semiconductor has the driving circuit and the pixel portion on the same substrate. It is characterized in that the storage capacitance is formed between the first electrode formed on the same layer as the light blocking film and the second electrode formed from a semiconductor film of the same composition as the drain region, and the first base insulating film is removed at the part of the storage capacitance so that the second base insulating film is used as the dielectric of the storage capacitance. This structure provides a large storage capacitance in a small area.
