A light emitting device including a light emitting unit and a phosphor resin layer is provided. The light emitting unit has a top surface and a bottom surface opposite to each other. Each of the light emitting units includes two electrodes. The two electrodes are disposed on the bottom surface. The phosphor resin layer is disposed on the top surface of the light emitting unit. One side of the phosphor resin layer has a mark. One of the two electrodes is closer to the mark with respect to the other one of the two electrodes.

Light emitting apparatus and manufacturing method thereof

A light-emitting device including at least one light-emitting unit, a wavelength conversion adhesive layer, and a reflective protecting element is provided. The light-emitting unit has an upper surface and a lower surface opposite to each other. The light-emitting unit includes two electrode pads, and the two electrode pads are located on the lower surface. The wavelength conversion adhesive layer is disposed on the upper surface. The wavelength conversion adhesive layer includes a low-concentration fluorescent layer and a high-concentration fluorescent layer. The high-concentration fluorescent layer is located between the low-concentration fluorescent layer and the light-emitting unit. The width of the high-concentration fluorescent layer is W. The width of the low-concentration fluorescent layer is W. The width of the light-emitting unit is W. The light-emitting device further satisfies the following inequalities: W&#x3c;W, W&#x3c;Wand 0.8&#x3c;W/W&#x2264;1.2. Furthermore, a manufacturing method of the light-emitting device is also provided.
