Abstract: A display apparatus includes: a first substrate on which a light-emitting device is located; and a light controller on the first substrate and corresponding to the light-emitting device. The light controller includes: an organic capping layer; a quantum dot layer and/or a scattering layer; and a color filter layer. The organic capping layer is adjacent to the quantum dot layer and/or the scattering layer.

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.
