Abstract:
1. A light emitting device comprising: a transmissive substrate; a light emitting structure layer on the transmissive substrate, the light emitting structure layer comprising a first conductive type semiconductor layer, 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 a top surface of the light emitting structure layer and connected to the second conductive type semiconductor layer; a plurality of first electrodes disposed in the transmissive substrate and extended from a lower part of the transmissive substrate to a lower part of the first conductive type semiconductor layer, the plurality of first electrodes being disposed under a region of the active layer; and a first electrode layer disposed under the transmissive substrate and connected to the plurality of first electrodes, wherein the plurality of first electrodes are overlapped with different regions of the second electrode in a vertical direction and are connected to the first conductive type semiconductor layer, wherein a top surface of the transmissive substrate includes a first region and a second region which are vertically overlapped with the first electrode layer, wherein the first region is vertically overlapped with the light emitting structure layer, wherein the second region is not vertically overlapped with the light emitting structure layer, wherein the second region is located at a position more on an outer side relative to the first region.
