Organic-inorganic hybrid coating layer, quantum dot nanocapsule, quantum dot light emitting diode package, and method of fabricating the same

A method of fabricating a quantum dot nanocapsule, the method comprising:

• preparing a first sol composition by mixing a first capsule composition of an organic substance and a second capsule composition of an inorganic substance;
• preparing a second sol composition by mixing quantum dots and additives in the first sol composition;
• photopolymerizing the second sol composition to form a structure in which the first capsule composition and the second capsule composition are crosslinked, and
• simultaneously introducing the quantum dots into the structure to form a bulk capsule structure in which the quantum dots are encapsulated into the structure;
• forming quantum dot microcapsules by pulverizing the bulk capsule structure;
• and
• preparing quantum dot nanocapsules by re-dispersing the quantum dot microcapsules in a solvent.
