A quantum dot manufacturing method comprises (a) dispersing, in a solvent, nano-seed particles whose crystal planes are exposed, and (b) growing semiconductor layers on the exposed crystal planes of the nano-seed particles in the solvent.

A quantum dot includes a nano-seed particle having a particular crystal plane exposed, and a first epitaxial layer formed on the particular crystal plane of the nano-seed particle.
