摘要： A method for manufacturing light emitting device is provided. Firstly, provide a substrate. Then arrange a light emitting unit on the substrate. Next form at least one electrode and arrange at least one protective layer on the electrode. The protective layer is to prevent a phosphor layer following formed on the light emitting unit from covering the electrode. After forming the phosphor layer, flatten the phosphor layer and the protective layer. A part of the phosphor layer over the protective layer is removed. Thus the electrode is not affected by the phosphor layer and conductivity of the electrode is improved to resolve phosphor thickness and uniformity problems of the light emitting device. Therefore, the thickness of the light emitting device with LED is effectively reduced and stability of white color temperature control is significantly improved.
