Abstract:
A semiconductor device comprising:a thin film transistor provided between an element to be driven which operates based on supplied power and which comprises an emissive element which includes an emissive element layer between a first electrode and a second electrode and a power supply line for supplying power to said element to be driven, for controlling the power supplied to said element to the driven; wherein the thin film transistor and said first electrode of corresponding element to be driven are electrically connected to each other by a wiring layer; said wiring layer is connected to said thin film transistor through a contact hole formed in a first insulation layer which covers said thin film transistor and is connected to said first electrode or said element to be driven formed on a second insulation layer through a contact hole formed in said second insulation layer which is formed above said wiring layer to cover said wiring layer; the contact position between the wiring layer and the thin film transistor is placed to be distant from the contact position between the wiring layer and said element to be driven in the horizontal direction and outside the formation region of said first electrode in the horizontal direction; and said emissive element layer mid said second electrode are layered on said first electrode formed on said second insulation layer.
