1. A semiconductor light emitting device comprising:

  • a base substrate;

    a multilayer epitaxial structure that includes a first conductive layer, a second conductive layer and a light emitting layer that is formed between the first conductive layer and the second conductive layer, the multilayer epitaxial structure being formed on the base substrate in such a manner that the first conductive layer is positioned closer to the base substrate than the second conductive layer is;

    a phosphor film that covers a main surface of the multilayer epitaxial structure which faces away from the base substrate, and every side surface of the multilayer epitaxial structure from a layer including the main surface to include at least the light emitting layer; and

    the multilayer epitaxial structure is shaped as a cylinder having a substantially circular or N-sided polygonal cross-section where N is an integer equal to or larger than five.
