Abstract
A color conversion substrate includes a base on which first to third light outputting regions and a light shielding region surrounding the first to third light outputting regions are defined; first to third color filters on the base in the first to third light outputting regions, respectively; a first light shielding member on the first color filter in the light shielding region; a light transmission pattern on the first color filter; a first wavelength conversion pattern on the second color filter and which converts light of a first color into light of a second color; and a second wavelength conversion pattern on the third color filter and which converts the light of the first color into light of a third color. A first opening located in the light shielding region is defined in at least one of the light transmission pattern and the first and second wavelength conversion patterns.
