Abstract:
1. A light emitting device chip, comprising: a light emitting structure including a first conductive semiconductor layer, a second conductive semiconductor layer and an active layer interposed between the first and second conductive semiconductor layers; at least two first electrodes on a top surface of the light emitting structure; a transmittive layer on the light emitting structure; and a luminescence material layer on the transmittive layer, wherein the luminescence material layer comprises a pattern, wherein the luminescence material layer partially exposes both the transmittive layer and the light emitting structure, wherein a bottom surface of the transmittive layer is disposed on a top surface of the light emitting structure, wherein the pattern of the luminescence material layer comprises at least two holes exposing the transmittive layer, wherein the at least two holes vertically overlap with the at least two first electrodes, and wherein the transmittive layer has lower thermal conductivity and higher light transmittive property than the luminescence material layer.
