    摘要: A light emitting device includes: a light emitting layered structure; an electrode unit connected to the light emitting layered structure and including a transparent electrode layer of a primary metal oxide which is stacked on the light emitting layered structure along a stacking direction; and a total-internal-reflection suppression material dispersed in the transparent electrode layer and containing a secondary metal oxide that is different from the primary metal oxide. The secondary metal oxide has a concentration gradient within the transparent electrode layer along the stacking direction. The light output power of the light emitting device may be increased by about 44% as compared to a conventional light emitting device.
