发明名称 Current-driven display device
摘要 In one embodiment of the present invention, 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 is disclosed. A driving TFT, a switching TFT, and an organic EL element are provided between a power supply wiring line and a common cathode, and a capacitor and a switching TFT are provided between a gate terminal of the driving TFT and a data line. A switching TFT is provided between a connection point B between the capacitor and the switching TFT and a reference supply wiring line, a switching TFT is provided between the gate terminal and a drain terminal of the driving TFT, and a switching TFT is provided between the gate terminal of the driving TFT and the connection point B.
