Abstract: A display device includes a display panel that includes a first light emitting region and a second light emitting region, each of which emits first color. A first partition wall is disposed on the display panel, which allows the first color light to be transmitted therethrough, and which has a first opening defined therein and that corresponds to the first light emitting region. A first light conversion pattern is disposed inside the first opening and converts the first color light into second color light having different color. A reflection pattern is disposed corresponding to an outer surface of the first partition wall and a top surface of the first partition. An organic material pattern is disposed on the top surface of the first partition wall and overlaps the reflection pattern. A first color filter is disposed on the first light conversion pattern and allows the second color light to be transmitted therethrough.

Abstract: A color conversion panel includes a substrate including first and second light emitting regions, banks partitioning the first and second light emitting regions, each bank among the banks including a bank light transmission layer, a metal layer on the bank light transmission layer and a transparent layer on the metal layer, a color conversion layer in the first light emitting region, and a light transmission layer in the second light emitting region. The bank light transmission layer and the light transmission layer are respective portions of a same material layer on the substrate.

Abstract: A display device includes a first substrate, on which first to third sub-pixel areas spaced apart from each other and a non-emission area corresponding to a boundary of the first to third sub-pixel areas are defined, a display element layer including a light emitting element disposed in each of the first to third sub-pixel areas on the first substrate, and a color-filter layer disposed on the display element layer. The color-filter layer includes a base layer, a first color filter disposed on the base layer and corresponding to the first sub-pixel area, a second color filter disposed on the base layer and corresponding to the second sub-pixel area, a first planarization layer covering the first color filter and the second color filter, a third color filter disposed on the first planarization layer and corresponding to the third sub-pixel area, and a second planarization layer covering the third color filter.
