Classification: CPC G | IPC G

Claim 7:
8. The display device according to claim 1, wherein
the display portion further includes:
a first power line configured to supply a high-voltage side power supply voltage,
a second power line configured to supply a low-voltage side power supply voltage, and
a low-voltage-side voltage line configured to supply a predetermined low-voltage-side voltage corresponding to the initialization voltage,

the emission control switching element and the display element initialization switching element are N-channel transistors,
a first electrode of the display element is connected to the first power line via the emission control switching element and is connected to the corresponding emission control line via the display element initialization switching element, and a second electrode of the display element is connected to the second power line,
a control terminal of the display element initialization switching element is connected to the low-voltage-side voltage line, and
the low-voltage-side voltage is higher than a voltage of the corresponding emission control line at a level for turning off the emission control switching element such that the display element initialization switching element is in an on-state when the voltage of the corresponding emission control line is at the level.
