Classification: CPC G | IPC G

Claim 11:
12. A display device comprising:
a display panel including pixel circuits;
a data driver which provides a data voltage to each of the pixel circuits;
a gate driver which provides gate signals to each of the pixel circuits; and
a timing controller which controls the data driver and the gate driver,
wherein each of the pixel circuits includes:
a light-emitting element;
a write transistor which writes the data voltage;
a driving transistor which generates a driving current based on the data voltage and applies the driving current to the light-emitting element;
a first initialization transistor which applies 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 which receives 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 which receives a second signal; and
a second electrode connected to the control electrode of the blocking transistor.
