Abstract
A light-scattering body includes at least light-transmitting resin, and first particles and second particles which are dispersed in the light-transmitting resin. An average grain size Da of the first particles is greater than an average grain size Db of the second particles. A refractive index na of the first particles is less than a refractive index nb of the second particles. The average grain size Db of the second particles is within a range of 150 nm≦Db≦300 nm.
