Abstract
A pixel circuit includes a driving transistor, a second transistor operating in response to the first gate signal, a third transistor operating in response to the second gate signal, a fourth transistor operating in response to an initialization control signal, a fifth transistor operating in response to an emission control signal, a sixth transistor operating in response to the emission control signal, a seventh transistor operating in response to a bias control signal, a storage capacitor, a first capacitor or a second capacitor, and a light emitting element. The first capacitor or the second capacitor includes a first terminal receiving the first gate signal or the emission control signal and a second terminal connected to a first terminal of the light emitting device, and the voltage of the first terminal of the light emitting element is boosted based on the first gate signal or the light emission control signal.
