1. A light emitting diode comprising:
a first electrode;
a hole transport region on the first electrode;
an emission layer on the hole transport region and comprising a quantum dot complex;
an electron transport region on the emission layer; and
a second electrode on the electron transport region,
wherein the quantum dot complex comprises two or more quantum dots each comprising a core and a shell around the core, and
wherein, of the two or more quantum dots, a shell of one quantum dot is directly combined with a shell of at least one neighboring quantum dot without another material therebetween.
