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 display device includes a base substrate, a plurality of display elements, a first light control layer, and a second light control layer. The base substrate includes a pixel region and a peripheral region adjacent to the pixel region. The display elements are disposed on the base substrate, overlap the pixel region in a plan view, and are configured to generate a first light. The first light control layer is disposed on the display elements, and includes a transmission part configured to transmit the first light, a first light conversion part configured to convert the first light into a second light, and a second light conversion part configured to convert the first light into a third light. The second light control layer overlaps at least a portion of the first light conversion part in the plan view and is configured to convert the first light into the second light.

Abstract: A quantum dot composition includes a scatterer containing an inorganic material, a quantum dot containing 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 containing at least one of an acidic substituent or a basic substituent. At least one of the polymer resin or the dispersant includes a same material as the shell and the ligand binds to the polymer resin or dispersant that includes the same material as a shell.
