Abstract: The present disclosure relates to an inorganic light emitting diode (LED) in which an emitting material layer (EML) includes inorganic luminescent particles dispersed in a siloxane matrix, wherein the siloxane matrix has a thickness equal to or less than a thickness of a layer of the inorganic luminescent particles, and an inorganic light emitting device including the inorganic LED. The siloxane matrix allows surface defects of the inorganic luminescent particles to be minimized and to prevent injections of holes and electrons from being delayed. The inorganic LED and the inorganic light emitting device lower their driving voltages and improve their luminous efficiency.
