Abstract
A color substrate and a display device including the same. The color substrate includes: a substrate including first and second pixel regions spaced apart from each other, and a light shielding region between the first and second pixel regions; a first color conversion layer over the first pixel region and configured to convert incident light into first color light; a second color conversion layer over the second pixel region and configured to convert the incident light into second color light; and a retroreflective layer over the light shielding region and configured to retroreflect incident light through the first and second color conversion layer.
