1. A sub-pixel comprising:
a light emitting element;
a first transistor configured to apply a driving current to the light emitting element, the first transistor comprising a first electrode to receive a first power voltage, a second electrode electrically connected to a second node, and a control electrode electrically connected to a first node;
a second transistor configured to write a data voltage in response to a write gate signal;
a first capacitor electrically connected to the control electrode of the first transistor;
a second capacitor including a first electrode electrically connected to the second transistor and a second electrode electrically connected to the control electrode of the first transistor;
a third transistor to diode-connect the first transistor in response to a compensation gate signal, the third transistor comprising a control electrode to receive the compensation gate signal, a first electrode electrically connected to the second node, and a second electrode electrically connected to the first node;
a fourth transistor configured to apply a first initialization voltage to the first electrode of the third transistor in response to an initialization gate signal, wherein the compensation gate signal and the initialization gate signal are different from each other; and
a fifth transistor configured to transfer the driving current to the light emitting element in response to an emission signal.
