Original Abstract Submitted
The present application discloses a current-driven display device employing an internal compensation method capable of achieving high-resolution of the display image while suppressing a reduction in the yield of manufacturing, the deterioration in display quality, an increase in the circuit amount. In a pixel circuit of an organic EL display device, a voltage of the gate terminal of a drive transistor is initialized before the voltage of a data signal line is written into a holding capacitor via the drive transistor in a diode-connected state. At this time, a current flows from the holding capacitor connected to the gate terminal of the drive transistor to an initialization voltage line via a threshold compensation transistor, a second light emission control transistor, and a display element initialization transistor, and the voltage Vg of the gate terminal is initialized. Thus, an initialization transistor provided between the gate terminal and the initialization voltage line in the related art comes to be unnecessary.
