Abstract:
1. A pixel circuit comprising: a driving transistor for making a current according to a gate voltage to flow into a driven element; a resistive element electrically connected in series to the driven element; a capacitive element whose one end is connected to a gate of the driving transistor; a switching transistor provided between the gate of the driving transistor and a data line to be turned on/off; and a single pole double throw switch whose common port is connected to the other end of the capacitive element, one port is connected to a potential line held with a predetermined potential, and the other port is connected to one end of the resistive element, a selection period and a non-selection period of a first frame and a selection period and a non-selection period of a second frame being continuous, during the selection period of the first frame, the switching transistor being turned on and a voltage according to a target current flowing in the driven element being applied to the data line, during the non-selection period of the first frame, the switching transistor being turned off, during the selection period of the second frame, the switching transistor being turned on, and during the non-selection period of the second frame, the switching transistor being turned off, the signal pole double throw switch closing the common port and the one port thereof during the selection period and the non-selection period of the first frame and the non-selection period of the second frame, and closing the common port and the other port during the selection period of the second frame.
