Abstract
A pixel includes a capacitor including a first electrode and a second electrode, a first transistor which generates a driving current, a second transistor which applies a data voltage to the first electrode of the capacitor, a third transistor which applies an initialization voltage to the second electrode of the capacitor, a fourth transistor which generates a leakage current in response to a dimming signal, and a light emitting element which emits light based on a residual driving current, where the residual driving current is obtained by subtracting the leakage current from the driving current.
