To allow a circuit that compensates for variations in a threshold voltage of a drive element to operate properly and prevent luminances of other pixel circuits from fluctuating due to a compensation operation, a pixel circuit 100 is made as follows. A driving TFT 110, a switching TFT 115, and an organic EL element 130 are provided between a power supply wiring line Vp and a common cathode Vcom, and a capacitor 120 and a switching TFT 111 are provided between a gate terminal of the driving TFT 110 and a data line Sj. A switching TFT 112 is provided between a connection point B between the capacitor 120 and the switching TFT 111 and a reference supply wiring line Vref, a switching TFT 113 is provided between the gate terminal and a drain terminal of the driving TFT 110, and a switching TFT 114 is provided between the gate terminal of the driving TFT 110 and the connection point B.
