Light-emitting device and manufacturing method thereof

A light-emitting device, comprising:

• a light-emitting element, comprising a first upper surface, a bottom surface and a plurality of first lateral surfaces between the upper surface and bottom surface;
• a wavelength conversion layer comprising a plurality of wavelength conversion particles and a second upper surface arranged on the first upper surface of the light-emitting element;
• and
• a light-adjusting layer, surrounding the plurality of first lateral surfaces in a configuration of exposing the second upper surface, and comprising an inner surface and an outer lateral surface, and a first composition or a second composition wherein the light-adjusting layer allows light to enter into the inner surface, travel through the light-adjusting layer, and depart from the outer lateral surface,
• wherein the first composition includes a first binder and a plurality of first light-diffusing particles, and a weight percentage of the first light-diffusing particles to the light-adjusting layer is not less than 20%;
• wherein the second composition includes a second binder, a plurality of second light-diffusing particles, and a plurality of light-scattering particles, a weight percentage of the second light-diffusing particles to the light-adjusting layer is not less than 5%, and a weight percentage of the light-scattering particles to the light-adjusting layer is not less than 0.4%.
