1. A light emitting display device, comprising:
a substrate;
a light emitting diode over the substrate; and
a color conversion layer between the substrate and the light emitting diode or over the light emitting diode and including a plurality of luminous bodies,
wherein each luminous body includes:
a plurality of emission moieties, each emission moiety including an inorganic emission particle and a coating layer surrounding a surface of the inorganic emission particle, and
an encapsulation moiety connected to or combined with the coating layer of the plurality of emission moieties by a covalent bond and surrounding the plurality of emission moieties,
wherein the inorganic emission particle comprises a core and a shell surrounding the core,
wherein the coating layer covers the shell and surrounds an outer surface of the inorganic emission particle,
wherein the coating layer includes a material selected from the group consisting of SiO2, TiO2, Al2O3, ZrO2, ZnO, niobium, zirconium, cerium and silicate,
wherein each luminous body further includes a curable moiety connected to an outer surface of the coating layer by a covalent bond,
wherein the coating layer is modified to include a hydroxyl group at a surface of the coating layer, and
wherein the encapsulation moiety comprises a silicone-based material.
