Abstract
A light-emitting device having an LED element and a resin layer including a convex portion covering the LED element can suppress color unevenness to achieve light emission with uniform color distribution. The light-emitting device can include a substrate, an LED element mounted on the substrate, a resin layer which contains a wavelength conversion material and is formed on the substrate to cover the LED element, the resin layer including a convex portion directly covering the LED element and a flat thin film portion extending around the convex portion, and a reflective portion which is formed over the thin film portion around the convex portion. A diffusion portion can be formed to cover the convex portion of the resin layer.
