Abstract:
1. A semiconductor light emitting device comprising: a light emitting structure including a first conductive type semiconductor layer, a second conductive type semiconductor layer, and an active layer between the first and second conductive type semiconductor layers; an electrode on a top surface of the first conductive type semiconductor layer; a reflective layer on a first lower surface of the second conductive type semiconductor layer; a conductive support member under a lower surface of the reflective layer; and a protective layer including a first portion on a second lower surface of the second conductive type semiconductor and a second portion that extends from the first portion to outwardly beyond the second lower surface of the second conductive type semiconductor layer, wherein a first light extraction structure directly contacts an upper surface of the second portion of the protective layer, wherein an entire region of the first light extraction structure is located at a lower position than a lower surface of the first conductive type semiconductor layer, wherein the first light extraction structure is located at an outer position than an outer sidewall of the light emitting structure, wherein the first light extraction structure includes a material different from the protective layer, and wherein the protective layer includes a transmissive material different from the second conductive type semiconductor layer.
