Quantum dot composition including a quantum dot, and a ligand having a head portion, a connecting portion including a metal, and a tail portion

A light emitting element comprising:

• a first electrode;
• a hole transport region on the first electrode;
• an emission layer on the hole transport region, the emission layer comprising a quantum dot comprising a hydrophilic group;
• an electron transport region on the emission layer;
• and
• a second electrode on the electron transport region.

A method for manufacturing a light emitting element, the method comprising:

• forming a first electrode;
• forming a hole transport region on the first electrode;
• forming an emission layer, the forming of the emission layer comprising providing, on the hole transport region, a quantum dot composition comprising a quantum dot composite comprising a quantum dot and a ligand bonded to a surface of the quantum dot;
• forming an electron transport region on the emission layer;
• and
• forming a second electrode on the electron transport region,
• wherein the ligand comprises:
• a head portion bonded to the surface of the quantum dot;
• a connecting portion connected to the head portion and comprising a metal;
• and
• a tail portion coordinated to the metal of the connecting portion.
