Patent ID: 10658392

Abstract:
A micro light-emitting diode display device including a driving transistor and a micro light-emitting diode is provided. The driving transistor includes a substrate, a bottom gate, a gate insulator, a semiconductor layer, an etch stopper, a drain electrode, a source electrode, and an insulating layer. The drain electrode is ring-shaped and a contact portion between the drain electrode and the semiconductor layer surrounds the semiconductor layer. The source electrode is in contact with the semiconductor layer and is enclosed by the drain electrode. The insulating layer has a via therein to expose a portion of the source electrode. The micro light-emitting diode is electrically connected to the source electrode. The micro light-emitting diode includes a current injection channel present in the micro-light emitting diode. The current injection channel is separated from a side surface of the micro light-emitting diode.
