Abstract
A color conversion particle includes: a particle body that contains a chalcogenide perovskite and emits light in response to excitation light received; and a shell that is formed of a semiconductor material for transmitting the excitation light and covers the particle body to inactivate defects on the surface of the particle body. The shell has a band gap more than 2.7 eV.
