Abstract
A display device includes a first pixel. The first pixel includes a first light emitting unit electrically connected between a first power line and a second power line. A first driving transistor is electrically connected between the first power line and the first light emitting unit, and controls a current flowing into the first light emitting unit, based on a first data signal from a first data line to a gate electrode. A first initialization transistor is electrically connected between the gate electrode of the first driving transistor and a third power line. A first switching transistor is electrically connected between a first electrode of the first light emitting unit and a first sub-power line. The first light emitting unit includes light emitting elements. The first driving transistor includes a first semiconductor material, and the first initialization transistor includes a second semiconductor material different from the first semiconductor material.
