Abstract
The present invention provides a semiconductor device which can prevent a current from flowing into a display element at a signal writing operation, without increasing power consumption and without changing a potential of a power supply for supplying a current to a load in each row. When a predetermined current is supplied to a transistor to set a gate-source voltage of the transistor, a potential of a gate terminal of the transistor is adjusted so as to prevent a current from flowing into a load which is connected to a source terminal of the transistor. Thus, a potential of a wire connected to the gate terminal of the transistor is made different from that of a wire connected to a drain terminal of the transistor. At that time, an operation of a transistor is shifted so as to allow a large amount of current to flow, and influences by intersection capacitance parasitic to a wire or the like or wire resistance are hardly caused, and a set operation is conducted quickly.
