Claim 14:
15. A light emitting device comprising:
a first electrode and a second electrode facing each other; and
a light emitting layer between the first electrode and the second electrode and comprising a plurality of quantum dots,
wherein the plurality of quantum dots comprises a first quantum dot and a second quantum dot, each of the first and second quantum dots comprises:
a core;
a first shell layer configured to surround the core;
a second shell layer configured to surround the first shell layer; and
a third shell layer configured to surround the second shell layer,

wherein a band gap of the second shell layer is greater than a band gap of the first shell layer and is greater than a band gap of the third shell layer, and
wherein a distance between the core of the first quantum dot and the core of the second quantum dot ranges from about 5 nm to about 15 nm.
