The semiconductor nanocrystals are quantum dot phosphors having fluorescence excitation spectra that differ depending on particle size of the quantum dot phosphors.

This makes it possible to uniformly disperse the semiconductor nanocrystals in a highly dense and highly uniform state, which contributes to implementing a thin fluorescent film having high reliability, high efficiency, and high color rendering properties.
