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.
