    Abstract: A color conversion substrate for displaying a first color, a second color, and a third color may include a base substrate, a first light-blocker, a second light-blocker, a pattern layer, a first color converter, and a second color converter. The first light-blocker contacts a surface of the base substrate and may block first light of the third color. The second light-blocker contacts the surface of the base substrate and may block second light of the third color. The pattern layer is disposed on the first light-blocker and the second light-blocker and includes an optical pattern that includes protrusions. The first color converter overlaps the first light-blocker and may convert a first portion of incident light into light of the first color. The second color converter overlaps the second light-blocker and may convert a second portion of the incident light into light of the second color.
