In a write period, a write current is caused to flow through a video signal line (DL) in a first state where a first control terminal and an output terminal of a drive control element (DR1), a second control terminal of a drive control element (DR2), and a video signal line (DL) are connected one another and a potential of a scan signal line (SL1) is set at a first potential, and the potential of the scan signal line (SL1) is shifted from the first potential to a second potential in a second state where the first and second control terminals, the output terminal, and the video signal line (DL) are disconnected from one another are sequentially executed. In a effective display period, a drive current is caused to flow through a display element (OLED) while keeping the potential of the scan signal line (SL1) at the second potential.During a writing period, a writing current is permitted to flow in a video signal line (DL) in a first status wherein first control terminal and output terminal of a drive control element (DR1), a second control terminal of a drive control element (DR2) and a video signal line (DL) are mutually connected and a potential of a scan signal line (SL1) is set at a first potential; and the potential of the scan signal line (SL1) is changed from the first potential to the second potential in a second status wherein connections among the first and the second control terminals, the output terminal and the video signal line (DL) are interrupted. During an effective display period, a drive current is permitted to flow in a display element (OLED) in a status wherein the potential of the scan signal line (SL1) is kept at the second potential.
