Abstract:
1. A light emitting device comprising: a substrate; a light emitting structure layer including a first conductive type semiconductor layer formed on the substrate and having first and second upper surfaces, in which the second upper surface is closer to the substrate than the first upper surface, an active layer on the first conductive type semiconductor layer, and a second conductive type semiconductor layer on the active layer; a second electrode on the second conductive type semiconductor layer; a plurality of first electrodes extending at least from the second upper surface of the first conductive type semiconductor layer to a lower surface of the substrate by passing through the substrate; an inclined side surface between the first and the second upper surfaces of the first conductive type semiconductor layer; and a first conductive layer disposed on the second upper surface of the first conductive type semiconductor layer and the inclined side surface and connected to the plurality of first electrodes, wherein the upper portions of the plurality of first electrodes are spaced apart from each other.
