  • Light-emitting device and manufacturing method thereof
    Patent number: 10312423
    Abstract: A light-emitting device includes a light-emitting element, a wavelength converting layer and a light-adjusting layer. The light-emitting element has a first upper surface, a bottom surface, and a lateral surface between the first upper surface and the bottom surface. The wavelength converting layer includes a plurality of wavelength converting particles, and has a second upper surface on the first upper surface. The light-adjusting layer surrounds the lateral surface and has a first composition or a second composition. The first composition includes a first binder and a plurality of first light-diffusing particles. The second composition includes a second binder, a plurality of second light-diffusing particles, and a plurality of light-scattering particles.
