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.

Abstract
An LED array chip (2), which is one type of a semiconductor light emitting device, includes an array of LEDs (6), a base substrate (4) supporting the array of the LEDs (6), and a phosphor film (48). The array of LEDs (6) is formed by dividing a multilayer epitaxial structure having a N-sided polygonal cross-section where N is an integer equal to or larger than 6. The phosphor film (48) covers an upper surface of the array of the LEDs (6) and a part of every side surface of the array of LEDs (6). Here, the part extends from the upper surface to the light emitting layer.
