Abstract: A pixel capable of displaying an image with uniform brightness. The pixel includes an organic light emitting diode (OLED), a first transistor controlling an amount of current that flows from a second node coupled to a first power supply to a second power supply via the OLED to correspond to a voltage applied to a first node, a second transistor coupled between the first node and an initializing power supply, and a third transistor turned on to supply a predetermined voltage to the second node at the moment when the second transistor is turned on.

Abstract: A first constant potential wiring that supplies a first constant potential to a scanning line drive circuit and a second constant potential wiring that supplies the first constant potential to a clock buffer circuit are electrically separated from each other.
