Abstract
A display device includes the following elements: a light emitting diode; a first transistor including a drain electrode, a source electrode, and a gate electrode, the drain electrode being connected to the light emitting diode; a second transistor connected between a data line and the source electrode; a third transistor connected between the drain electrode and the gate electrode; and a fourth transistor connected between a first initialization voltage source and the gate electrode. The third transistor is off for a first period, on for a second period immediately following the first period, and off for a third period immediately following the second period. The fourth transistor is off for a fourth period, on for a fifth period immediately following the fourth period, and off for a sixth period immediately following the fifth period.
