Abstract
Provided is a light emitting device that reduces color unevenness between a plurality of light emitting elements. A light emitting device 1 includes a base substrate 10, a first frame body 11 disposed at an upper surface 10a of the base substrate 10, and a second frame body 12 disposed at 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 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 light emitting elements 2. The first sealing resin 21 includes a wavelength conversion member that converts a wavelength of light emitted from the 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.
