Abstract

A pixel includes a light emitting element, first through third transistors, sixth through seventh transistors, a ninth transistor, and a capacitor. The first transistor is connected between supply and a second node and controls a driving current supplied to the light emitting element. The second transistor is connected between a third node and a data line. The third transistor is connected between a first node connected to a gate electrode of the first transistor and the second node. The sixth transistor is connected between the supply and a fifth node connected to an electrode of the first transistor. The seventh transistor is connected between the second node and a fourth node connected to an anode of the light emitting element. The ninth transistor is connected between the fifth node and bias. Gate electrodes of the sixth through seventh transistors and the ninth transistor are connected to a same emission line.
