Abstract: A display device may include a first substrate, a first color conversion unit, a second color conversion unit, a light diffusion unit, and a first wall. The first color conversion unit is located on the first substrate. The second color conversion unit is disposed on the first substrate and is spaced from the first color conversion unit. The light diffusion unit is disposed between the first color conversion unit and the second color conversion unit. The first wall is disposed between the first color conversion unit and the light diffusion unit. The first color conversion unit includes a first-color conversion layer. The first-color conversion layer overlaps two pixel regions.
