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.

Abstract: A method of manufacturing a display device includes forming a color filter layer (CFL), and forming a light control layer (LCL) on the CFL. Forming the LCL includes: forming, on the CFL, preliminary partition parts (PPPs) spaced apart from each other; forming a preliminary light control part (PLCP) by providing a quantum dot (QD) solution between the PPPs, the QD solution including a QD and a base resin; forming a light control part (LCP) by volatilizing the base resin from the PLCP; and forming partition parts by reducing a thickness of the PPPs. A ratio between a first weight ratio (WR) of the QD in the PLCP and a second WR of the QD in the LCP is about 1:1.1 to about 1:3.0. The first WR is a WR of the QD in the entire PLCP, and the second WR is a WR of the QD in the entire LCP.

Abstract: A method of fabricating a display device may include the following steps: patterning a light blocking layer on a first surface of a first substrate, forming a color filter layer on a second surface of the first substrate opposite the first surface after the patterning of the light blocking layer, and forming a light conversion layer including a plurality of conversion filters on the first surface of the first substrate after the forming of the color filter layer. Each of the conversion filters may include a plurality of conversion particles, and the color filter layer may be formed to selectively transmit light emitted from each of the conversion filters.
