<p>Disclosed are a light emitting device having wide beam angle and uniform illumination, and a method of fabricating the same. The light emitting device includes: a light emitting structure and a transparent substrate located on the light emitting structure. The transparent substrate includes at least two different embossed patterns which include a first embossed pattern and a second embossed pattern located on its upper surface. The protrusion part of the first embossed pattern is larger than that of the second embossed pattern. The first embossed pattern is located in the center region of the upper side of the transparent substrate. The second embossed pattern is located in the edge region of the upper side of the transparent substrate. Thereby, the light emitting device has a wide beam angle and uniform illumination according to a light emitting angle.</p> |
