DISPLAY DEVICE AND DRIVE METHOD THEREFORA display device 100 includes a plurality of pixel5 circuits 10 arranged two-dimensionally; a plurality of power lines VPi provided for respective rows of the pixel circuits 10; p common power lines 9, each connected to two or more power lines VPi; and a power control circuit 4. Each pixel circuit 10 includes an organic EL element, a plurality of TFTs, and a10 capacitor and receives an initialization potential from a corresponding power line VPi. The power control circuit 4 applies a power supply potential and the initialization potential to the p common power lines 9 in a switching manner. Accordingly, a display device is provided that has a15 configuration in which an initialization potential is provided to pixel circuits from power lines and that has a power control circuit small in circuit size.Figure 1 |
