Quantum dot composition, method of manufacturing display device including the same, and display device manufactured by the display device manufacturing method

A display device manufacturing method comprising forming a light control layer,

• the forming of the light control layer including:
• forming a plurality of partition walls spaced apart from each other;
• and
• forming a light control part by providing a quantum dot composition between the partition walls,
• wherein the quantum dot composition includes:
• a scatterer that includes an inorganic material,
• a quantum dot that includes a core and a shell surrounding the core,
• a ligand binding to the quantum dot,
• a polymer resin in which the quantum dot and the scatterer are dispersed, and
• a dispersant that includes at least one of an acidic substituent or a basic substituent,
• wherein at least one of the polymer resin, the dispersant, or the partition walls comprises a same material as the shell.

A display device comprising:

• a display element layer;
• a color filter layer disposed on the display element layer;
• and
• a light control layer disposed between the display element layer and the color filter layer,
• the light control layer including:
• a plurality of partition walls spaced apart from each other, and
• a light control part disposed between the partition walls,
• the light control part including:
• a quantum dot containing a core and a shell surrounding the core,
• a scatterer containing an inorganic material,
• a polymer resin in which the quantum dot and the scatterer are dispersed,
• a dispersant containing at least one of an acidic substituent or a basic substituent, and
• a plurality of ligands binding to the surface of the shell or detached from the surface of the shell,
• wherein at least one of the polymer resin, the dispersant, or the partition walls comprises a same material as the shell, and
• at least one of the ligands binds to the polymer resin, dispersant, or partition walls including the same material as the shell.
