Abstract
A diffuser generates scattered light and satisfiesMFP=1/(π×)=α,0.4≤α≤5where N denotes a number of nanoparticles included in a unit volume of a light guiding and diffusing portion, A denotes an average particle radius of the nanoparticles, Qdenotes a scattering efficiency determined by a combination of the nanoparticles and a medium of the light guiding and diffusing portion, MFP denotes a mean free path for light of a design wavelength set in a range of 450 nm to 650 nm, Zdenotes a length of the light guiding and diffusing portion in a light guiding direction of incident light, and a denotes a coefficient.
