摘要： 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.

摘要： A display panel includes a display device layer including first to third light emitting areas and a non-tight emitting area and a light shielding member disposed on the display device laver. The light shielding member overlaps the non-light emitting area and includes light shielding openings corresponding to the first to third light emitting areas. A first portion of the light shielding member disposed between the first light emitting area and the second light emitting area has a first thickness at a first edge adjacent to the first light emitting area and a second thickness that is different from the first thickness at a second edge adjacent to the second light emitting area. A second portion of the light shielding member is disposed between the first light emitting area and the third light emitting area and has a uniform thickness.

摘要： A display apparatus includes a light-emitting element, an encapsulation layer covering the light-emitting element, a bank on the encapsulation layer and including an opening corresponding to the light-emitting element, and a quantum-dot layer in the opening of the bank. Roughness of a lower surface of the quantum-dot layer which is closest to the encapsulation layer is different from roughness of an upper surface of the quantum-dot layer which is furthest from the encapsulation layer.
