Abstract
A pixel includes a display element, a driving transistor which controls an amount of a driving current flowing toward the display element, a first capacitor connected to a gate of the driving transistor, a scan transistor which transfers a data voltage to a source of the driving transistor, first and second compensation transistors connected to each other in series between the gate and a drain of the driving transistor, first and second emission control transistors which generates a path of the driving current between the display element and a power line, and a second capacitor connected between a floating node between the first and second compensation transistors and a gate of the second emission control transistor.
