Abstract: The present invention provides a backlight unit capable of realizing a wide color gamut of a display device by reduction of the spectral half-width of light. The backlight unit provided by the present invention comprises: a light source which is formed so as to provide primary light; a quantum dot phosphor which is excited by the primary light provided from the light source and emits secondary light having a wavelength different from the wavelength of the primary light, the quantum dot phosphor being arranged so as to be spaced apart from the light source; and a light cutting agent which absorbs light of a specific wavelength from the primary light or the secondary light.

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.
