Abstract: A color conversion substrate and a display device including the same. The color conversion substrate includes a color filter layer having a plurality of color filters, and a color conversion layer disposed on the color filter layer. The color conversion layer includes a plurality of dams, and a plurality of conversion parts disposed between the dams. A reflection layer is disposed on the dams, and a hydrophobic area is disposed on the reflection layer, overlapping an upper surface of the dams, and non-overlapping a side surface of the dams. The display device further includes a light source configured to output a first color light to the color conversion substrate.

Abstract: A display device includes a substrate, a sub-pixel structure, a light blocking member, and a reflective member. A display area including a sub-pixel area is defined on the substrate. The sub-pixel structure is disposed in the sub-pixel area on the substrate. The light blocking member is disposed over the sub-pixel structure, and a first opening is defined in a portion of the light blocking member which overlaps the sub-pixel structure. The reflective member is disposed between the light blocking member and the sub-pixel structure, and the reflective member surrounds the sub-pixel structure and the first opening.

Abstract: A display device is provided including a substrate. The substrate includes a pixel area and a light-blocking area. A light-emitting element is arranged in the pixel area of the substrate. An insulating layer is disposed on the substrate. The insulating layer has an opening corresponding to the light-blocking area and an insulating pattern corresponding to the pixel area. A light control pattern at least partially surrounds the insulating pattern of the insulating layer and is arranged in the opening corresponding to the light-blocking area.

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.
