Abstract: A solventlesss quantum dot composition, a method for preparing the same, and a cured film, a color filter, and a display device including the same are disclosed. The solventless quantum dot composition comprises quantum dots surface-modified with at least two ligands, has low viscosity and good optical properties, and can be prepared by synthesis of quantum dots (QDs), followed by direct ligand substitution in the solution, thereby securing a simplified preparation process.

Abstract: A display apparatus includes a display panel; and a light control member disposed on the display panel. The light control member includes a plurality of partition walls spaced apart from each other, and a plurality of light control units each disposed between any two of the plurality of partition walls, and at least one of the plurality of light control units includes a first region containing organic monomers and an inorganic material and a second region containing the inorganic material dispersed in an organic polymer, thereby improving display quality and reliability of the display apparatus.
