Patent attributes
A light emitting device includes: a mounting board; a plurality of light sources positioned on the mounting board; a light diffusion plate; a half mirror positioned between the light diffusion plate and the plurality of light sources; and a plurality of diffuse reflectors positioned between the mounting board and the light diffusion plate, and above at least part of each emission face of the plurality of light sources. The diffuse reflectors comprise a resin, and particles dispersed in the resin. Each of the diffuse reflectors is positioned in an area that, in the top view, is larger than and includes the emission face of each light source. A density of the particles in said area, in the top view, is higher in a first portion located immediately above the emission face of each light source than in a second portion located around a periphery of the first portion.
