Abstract

A pixel circuit includes a light-emitting element, a write transistor writing a data voltage, a driving transistor generating a driving current based on the data voltage and applying the driving current to the light-emitting element, a first initialization transistor applying a first initialization voltage to a control electrode of the driving transistor, a blocking transistor disposed between the light-emitting element and the driving transistor, a first blocking control transistor including a control electrode connected to the control electrode of the driving transistor, a first electrode receiving a first signal, and a second electrode connected to a control electrode of the blocking transistor, and a second blocking control transistor including a control electrode connected to the control electrode of the driving transistor, a first electrode receiving a second signal, and a second electrode connected to the control electrode of the blocking transistor.
