Abstract
A pixel circuit includes a driving transistor, a first capacitor including a first electrode and a second electrode, a write transistor that writes a data voltage to a control electrode of the driving transistor in response to a write gate signal, a first emission transistor that provides a first power supply voltage to the second electrode of the first capacitor in response to a first emission signal, a first initialization transistor that provides a first initialization voltage to the control electrode of the driving transistor in response to an initialization gate signal, a second initialization transistor that provides a second initialization voltage to a second electrode of the driving transistor in response to a bias gate signal, and a light emitting element that emits light.
