Abstract: A color control member includes a color control layer including a quantum dot and a color filter layer on the color control layer, wherein a low refractive layer may be between the color control layer and the color filter layer. The low refractive layer includes a base resin and a plurality of sets of hollow particles dispersed in the base resin, and each of the hollow particles of each set of the sets of hollow particles may have a spherical shape. The sets of hollow particles may have respective average diameters, and a ratio of two average diameters of the respective average diameters of the sets of hollow particles is about 2:1 to about 60:1, and the low refractive layer including the hollow particles may be formed through a continuous process at a low temperature.
