The color conversion pattern may include a base resin and quantum dots, which are mixed or dispersed in the base resin. In the present embodiment, the color conversion pattern may include a quantum dot, and in this sense, the color conversion pattern may be referred to as a quantum dot pattern. The color conversion patterns of the first and second pixel regions may include different quantum dots from each other. The base resin may be a medium material, in which the quantum dots are dispersed, and may be formed of at least one of various resin composites, which may be called “binders”. However, the inventive concept is not limited to this example, and in the present specification, if the quantum dots can be dispersed in a medium material, the medium material may be referred to as a base resin, regardless of its name, additional function, or constituents. The base resin may be a polymer resin. For example, the base resin may be acrylic resins, urethane resins, silicone resins, and/or epoxy resins. The base resin may be transparent.

The color conversion pattern may include a base resin and a scattering particle mixed in the base resin, like the transmission pattern. The scattering particle may be a nano particle that is formed of or includes titanium oxide (TiO₂) or silica.
