Abstract
A pixel includes: an organic light emitting diode; a first transistor for controlling an amount of driving current flowing from a first voltage line connected to a second node to a second voltage line via the organic light emitting diode, corresponding to a voltage of a first node; a second transistor connected between a data line and the second node, the second transistor having a gate electrode connected to a first scan line; a third transistor connected between the first voltage line and a third node, the third transistor having a turn-on period that does not overlap with that of the second transistor; a fourth transistor connected to the third node, the fourth transistor having a gate electrode connected to the first scan line; a first capacitor connected between the first voltage line and the first node; and a second capacitor connected between the data line and the third node.
