Abstract: The present application discloses a current-driven display device capable of providing satisfactory display without flickering even when pause drive is performed. In a pixel circuit 15, a first initialization transistor T4 initializes a gate voltage Vg, and thereafter a voltage on a data signal line Di is written to a holding capacitor Cst via a write control transistor T2 and a drive transistor T1. Thereafter, emission control transistors T5 and T6 are turned on, so that a drive current I1 from the drive transistor T1 causes an organic EL element OL to emit light. During this emission period, even if the gate voltage Vg is decreased due to a leakage current through the first initialization transistor T4 in an OFF state, the decrease is compensated for by increasing a threshold control voltage being provided to a threshold control terminal TG of the drive transistor T1. Thus, even if the pause drive results in a long refresh cycle, it is possible to inhibit an increase in luminance due to the decrease in the gate voltage Vg and thereby prevent the occurrence of flickering.
