Abstract: A color conversion substrate includes a first bank structure, a second bank structure, a spacer, and a color conversion layer. The first bank structure includes a first partition wall that has a first opening area and a second opening area, and that divides the second opening area into a central area and a peripheral area that surrounds the central area. The second bank structure is spaced apart from the first partition wall and disposed in a central area of the second opening area. The spacer is disposed to overlap the second bank structure. The color conversion layer is disposed in the first opening area and includes a color conversion particle.
