Abstract
A micro light emitting diode chip including a first-type semiconductor layer, an active layer, a second-type semiconductor layer, a first-type electrode, and a second-type electrode is provided. The first-type semiconductor layer has a first high-concentration doping region and a first low-concentration doping region. The active layer is disposed between the first-type semiconductor layer and the second-type semiconductor layer. The first-type electrode is directly contacted and electrically connected to the first high-concentration doping region. The second-type electrode is electrically connected to the second-type semiconductor layer.
