PROBLEM TO BE SOLVED: To provide a semiconductor light emitting device where nonuniformity of light emission can be resolved by making spreading thickness of fluorescent substances uniform. SOLUTION: When a plurality of kinds of fluorescent substances are spread on the periphery of a light emitting element, mixing nonuniformity to be generated by difference of specific gravities and grain diameters of the respective fluorescent substances is prevented. For the structure, the light emitting element is mounted in such a manner that the element is buried in a mounting member. A plurality of fluorescent substances 13, 14, 15 are spread on a practically plane surface obtained by the above manner. Thereby a uniform mixture of the fluorescent substances 13, 14, 15 or spreading on uniform layers are possible, so that light emission free from color nonuniformity can be realized. |
