1. A perovskite color converter comprising:
a siloxane resin having a siloxane bond by a sol-gel reaction and a cross-linking reaction between silane precursors;
perovskite nanoparticles that perform a light-emitting operation; and
organic ligands surrounding the perovskite nanoparticle,
wherein the organic ligands are chemically cross-linked with the siloxane resin,
wherein the perovskite nanoparticles are dispersed in the cross-linked siloxane resin,
wherein the silane precursors are an organic alkoxysilane or an organic silanediol, and
wherein the organic ligand has an unsaturated carbon bond.
