The invention discloses a color conversion substrate and a display device including the same. A color conversion substrate includes: a substrate including first, second, and third light emitting regions and a light shielding region surrounding the first, second, and third light emitting regions; a first color filter layer under the substrate, overlapping the first light emitting region, and having a first opening exposing a portion of the substrate; a second color filter layer under the substrate and the first color filter layer, overlapping the second light emitting region, and having a second opening exposing a portion of the first color filter layer; and a third color filter layer under the substrate and the second color filter layer, overlapping the third light emitting region, and having a third opening exposing a portion of the second color filter layer and a fourth opening exposing a portion of the first color filter layer. In a plan view, a first shortest distance from an end of the first opening to a
