Abstract
According to an aspect, a method of preparing quantum dots includes a first operation of preparing a quantum dot seed solution; a second operation of growing a quantum dot by continuously injecting a quantum dot cluster solution into the quantum dot seed solution; a third operation of separating the grown quantum dot and dispersing the quantum dot in a solvent; and a fourth operation of further growing the quantum dot by continuously injecting the quantum dot cluster solution into the dispersed quantum dot.
