1. A light emitting device comprising:
a mounting board;
a light source positioned on the mounting board;
a light diffusion plate;
a diffuse reflector positioned between the mounting board and the light diffusion plate, and above at least part of an emission face of the light source, wherein:
in a top view, the diffuse reflector overlaps said at least part of the emission face of the light source,
the diffuse reflector comprises a resin, and reflecting particles dispersed in the resin, and
