Abstract: A display panel includes a display layer including a light emitting element generating a source light, a first color filter on the display layer, a first color control layer between the display layer and the first color filter and including a first surface facing the first display layer and a second surface facing the first color filter, and a plurality of capping layers encapsulating the first color control layer. Among the capping layers, a capping layer between the first surface of the first color control layer and the display layer has a first-first thickness that is different from a second-first thickness of a capping layer between the second surface of the first color control layer and the first color filter.

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.
