Abstract
A light-emitting module is provided. The light emitting module includes a substrate; a thin-film layer that is disposed above the substrate, the thin-film layer defining an opening that exposes a surface of the substrate; a light-emitting element disposed above the substrate and in the opening; and a sealant disposed above the substrate and in the opening, the sealant containing a wavelength converter and sealing the light-emitting element. A thickness of the thin-film layer is less than a thickness of the sealant. An edge portion of the sealant is in contact with the thin-film layer. The surface of the substrate and a surface of the thin-film layer are hydrophilic. The surface of the thin-film layer has a lower wettability than a wettability of the surface of the substrate.
