Abstract
A pixel for a display device includes a light-emitting element, a first transistor including a first electrode electrically connected to a first node and controlling a driving current, a second transistor electrically connected between a data line and the first node and being turned on in response to a first scan signal supplied through a first scan line, a third transistor electrically connected between the second node and a third node electrically connected to a second electrode of the first transistor and being turned on in response to the first scan signal, and a fourth transistor being turned on in response to a second scan signal supplied through a second scan line, and applying a bias voltage to the first transistor. The fourth transistor is turned on at a first frequency. The second and third transistors are turned on at a second frequency different from the first frequency.
