Abstract: A display panel includes a light-emitting element which outputs source light and includes a first electrode, a light-emitting layer disposed on the first electrode, and a second electrode disposed on the light-emitting layer, a light control layer disposed on the light-emitting element and including a first light control pattern which converts the source light into first light, and a second light control pattern which transmits the source light, and a color filter layer disposed on the light control layer and including a first color filter overlapping the first light control pattern, and a second color filter overlapping the second light control pattern. The first color filter has a light transmittance of 70% or less in a wavelength range of 600 nm to 640 nm, and the second color filter has a light transmittance of 75% or less in a wavelength range of 430 nm to 470 nm.

Abstract: A color control member includes a light control layer including quantum dots, a color filter layer disposed on the light control layer, and a low refractive layer disposed between the color filter layer and the light control layer. The low refractive layer includes a base resin, a plurality of non-hollow inorganic particles dispersed in the base resin and of which inner portions are filled. A weight percent of the base resin is in a range of about 40 wt % to about 45 wt % with respect to a total weight of the low refractive layer, and a weight percent of the non-hollow inorganic particles is in a range of about 40 wt % to about 45 wt % with respect to the total weight of the low refractive layer. The color control member including the low refractive layer has excellent reliability.
