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 display device includes a light-emitting element layer and a light control layer. The light control layer may include a plurality of separated partition wall parts including a partition wall part, a color control part between the partition wall parts, the color control part including quantum dots and a first scattering particle, and a coating layer covering a side of the partition wall part adjacent to the color control part. The coating layer includes at least one selected from a substitution dispersant and a substitution scattering particle, and each of the substitution dispersant and the substitution scattering particle may include at least one substituent selected from an amine group and a carboxyl group. The amine groups and the carboxyl groups included in the coating layer may be different in number from each other.
