Abstract: A quantum dot microcapsule according to an embodiment of the present invention includes one or more quantum dots each including a ligand coupled to an outer circumferential surface thereof, the ligand being made of an organic material, and a microcapsule accommodating the one or more quantum dots. The microcapsule includes an oil or a solvent with the quantum dots dispersed therein. There are effects capable of not only effectively adjusting a density of quantum dots through formation of a microcapsule formed to include one or more quantum dots and filled with an oil, but also effectively protecting ligands of the quantum dots from an environment such as oxygen, moisture or the like, against which the ligands are weak.
