1. A color conversion panel comprising: a base substrate; a low refractive index layer under the base substrate; a plurality of light blocking members spaced apart from each other in the low refractive index layer and extending in a first direction normal to a surface of the base substrate; a high refractive index layer under the low refractive index layer and comprising at least one convex portion, wherein the convex portion protrudes toward the base substrate; a color filter layer under the high refractive index layer; and a color conversion layer under the color filter layer that converts an incident light into a transmitted light, wherein the transmitted light has a second color different from a first color of the incident light, wherein the color filter layer is between the high refractive index layer and the color conversion layer along the first direction, and wherein each of the plurality of the light blocking members is to absorb at least a portion of an external light incident from an outside into the low refractive index layer through the base substrate at a side surface of the light blocking member.
