Abstract

Provided is a light emitting device that reduces the color unevenness between a plurality of semiconductor light emitting elements. A light emitting device (1) includes a base substrate (10), a first frame body (11) disposed on an upper surface (10a) of the base substrate (10), and a second frame body (12) disposed on the upper surface (10a) of the base substrate (10) and surrounding the first frame body (11) while being spaced away from the first frame body (11). A plurality of semiconductor light emitting elements (2) is disposed within a region surrounded by the first frame body (11). A first sealing resin (21) is disposed within the region surrounded by the first frame body (11) to cover the semiconductor light emitting elements (2). The first sealing resin (21) includes a wavelength conversion member that converts a wavelength of light emitted from the semiconductor light emitting elements (2). A second sealing resin (22) is disposed within the region surrounded by the second frame body (12) to cover the first sealing resin (21). The second sealing resin (22) has a light diffusion material layer (221) having a convex upper surface over the first sealing resin (21).
