Semiconductor device, display device and electronic device equipped with the semiconductor device

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