Abstract
A light emitting device including an active layer, a first semiconductor layer, a first contact layer, and a first current limiting layer is provided. The first semiconductor layer is disposed at a first side of the active layer. The first contact layer is disposed at a side of the first semiconductor layer away from the active layer. The first current limiting layer is disposed between the first contact layer and the active layer, and is provided with a first non-oxidizing region and a first oxidizing region located around the first non-oxidizing region. The first current limiting layer has a first surface facing the active layer and a second surface away from the first surface. The first oxidizing region is extended from the first surface to the second surface, and an oxygen content of the first oxidizing region is greater than an oxygen content of the first non-oxidizing region.
