The invention provides a light emitting diode with a large viewing angle and a fabricating method thereof. The light emitting diode includes a substrate, a plurality of pillar structures, a filler structure, a transparent conductive layer, a first electrode, and a second electrode. These pillar structures are formed on the substrate. Each of the pillar structures includes a first type semiconductor layer, an active layer, and a second type semiconductor layer. The first type semiconductor layers are formed on the substrate. The pillar structures are electrically connected with each other through the first type semiconductor layers. The filler structure is formed between the pillar structures. A surface passivation layer, an electrical isolation layer and a surface formed by the second type semiconductor layers in the pillar structures are covered with the transparent conductive layer covers. The first electrode is in contact with the transparent conductive layer. The second electrode is in contact with the first type semiconductor layer.
