1. A color conversion substrate comprising:
a base part in which a first light-transmitting area and a second light-transmitting area are defined;
a first stack disposed on the base part and a second stack disposed on the first stack;
a first wavelength conversion pattern overlapping the second light-transmitting area, and disposed on the second stack, wherein the first wavelength conversion pattern converts light of a first color into light of a second color; and
a light-transmitting pattern overlapping the first light-transmitting area and disposed between the first stack and the second stack,
wherein portions of the first stack and the second stack in the second light-transmitting area are in direct contact with each other to constitute a blue light reflective layer.
