Abstract: A color conversion substrate includes a base substrate including a display area and a non-display area which is adjacent to the display area in a first direction, a color filter layer in the display area, a light blocking member in the non-display area, extending in the first direction and defining a pattern groove of the light blocking member, the pattern groove being in the non-display area, and a refractive layer facing the base substrate with both the color filter layer and the light blocking member therebetween. The refractive layer extends into the pattern groove of the light blocking member and fills the pattern groove.
