PROBLEM TO BE SOLVED: To suppress a deviation of light emitted and a variation of chromaticity to improve manufacturing yield by improving mounting precision of a light converting member.SOLUTION: The semiconductor light emitting device includes: a light-emitting element; a rear surface electrode provided on a lower surface of the light-emitting element; a first phosphor layer provided on an upper surface of the light-emitting element; and a light control member covering a side surface of the light emitting element and the first phosphor layer. A lower surface of the light emitting element and at least a lower surface of a back surface electrode are exposed without being covered by the light control member.SELECTED DRAWING: Figure 1 【課題】光変換部材の搭載精度を向上させることにより、発光する光の偏り及び色度のばらつきを抑制し、延いては製造歩留まりを向上させる。【解決手段】発光素子と、該発光素子の下面に設けられた裏面電極と、前記発光素子の上面に設けられた第１の蛍光体層と、前記発光素子及び前記第１の蛍光体層の側面を覆う光制御部材と、を備え、前記発光素子の下面及び前記裏面電極の少なくとも下面が、前記光制御部材に覆われずに露出している半導体発光装置を提供する。【選択図】図１
