A light emitting deviceincludes a surface structurein a surface of a transparent substratewhich is adjacent to a light emitting body. The surface of the transparent substrateis divided into minute regions, without leaving any gap therebetween, such that the diameter of the largest one of the inscribed circles of the minute regions is from 0.2 μm to 1.5 μm. Each of the minute regions is in the form of a protrusion or recess. The proportion of the protrusions and the proportion of the recesses are P and 1−P, respectively, and P is in the range of 0.4 to 0.98. At least part of the minute regions has a micro periodic structurethat is formed by indentations and projections.
