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.
