A light emitting device includes a substrate having a top surface and an bottom surface and a light emitting structure on the substrate, disposed closer to the substrate top surface than the substrate bottom surface, having an n-type conductive type semiconductor layer, a p-type conductive type semiconductor layer, and an active layer. The light emitting device also includes a transparent electrode layer, a first electrode, and a second electrode. The substrate has side surfaces extending from the substrate bottom surface to the substrate top surface, the side surfaces inclined outwardly as the substrate extends in a direction from the substrate bottom surface to the substrate top surface. The transparent electrode layer overlaps more than 50% of a total area of the substrate bottom surface, and a part of light generated by the light emitting structure is emitted to outside via the transparent electrode layer.
