Zusammenfassung:A light-emitting device includes a light-emitting element, a wavelength conversion layer, a light pervious element and a light-reflecting enclosure. The light-emitting element includes a top surface, a bottom surface, and a side surface between the top surface and the bottom surface. The wavelength conversion layer covers the top surface of the light-emitting element, and includes a plurality of wavelength conversion particles having an equivalent particle diameter D50. The light pervious element includes a recess structure and an outer wall. The light-reflecting enclosure surrounds the outer wall. The D50 of the wavelength conversion particles is not great than 10 μm. The recess structure is laterally overlapped with the side surface of the light-emitting element and the wavelength conversion layer.
