摘要： 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.

摘要： 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.
