|Title:||QUANTUM DOT, POLYMER RESIN, QUANTUM DOT SHEET, AND BACKLIGHT UNIT INCLUDING SAME|
The present invention relates to a quantum dot, a polymer resin, a quantum dot sheet and a backlight unit including the same and, more specifically, to a quantum dot including an inorganic ion ligand, a polymer resin excellent in oxygen and moisture barrier properties, and a quantum dot sheet with improved light conversion efficiency, and a backlight unit including the same. The quantum dot of the present invention comprises: a core including a semiconductor material; and an inorganic ion ligand surrounding the surface of the core, wherein the inorganic ion ligand comprises a halogen group or chalcogen group elements. In addition, the polymer resin of the present invention is an acrylic-based resin containing an aromatic ring in its main chain. Further, in the backlight unit of the present invention, the quantum dot sheet is bonded on a light guide plate so that an air layer is formed between the light guide plate and the quantum dot sheet, and the light guide plate and the quantum dot sheet are fixed to each other.
