Abstract
The present invention discloses a micro LED structure including a first semiconductor layer, a first electrode, a second electrode, and an active layer. The first semiconductor layer has two opposite sides defined as a first surface and a second surface. The first semiconductor layer has a doped region located therein and exposed on the first surface. A pn junction is formed between the doped region and the first semiconductor layer. The first electrode and the second electrode, located on the first surface, are capable of electrically connecting to the first semiconductor layer and the doped region respectively. The active layer is adjacent to the second surface. Wherein the first semiconductor layer is a first doping type, and the doped region is a second doping type different from the first doping type, and the first semiconductor layer and the pn junction are located at identical side of the active layer.
