Abstract
A hybrid organic/inorganic quantum dot composite with high reliability is disclosed. The hybrid organic/inorganic quantum dot composite includes quantum dot, polymer resin, and silica, in which the silica is formed in the polymer resin, one end of the polymer resin forms a chemical bond with the quantum dot, and another end of the polymer resin includes a functional group capable of forming an additional chemical bond. The hybrid organic/inorganic quantum dot composite is resistant to moisture and oxygen permeation, and thus, it is not degraded easily by bonding oxygen and moisture to quantum dots even if moisture and oxygen permeate into the composite. The quantum dot composite may be used as a secondary raw material capable of being processed into another form while maintaining physical properties of quantum dots as a primary raw material.
