  • Patent number: 11950482
    Abstract: A color conversion panel includes a first color filter and a second color filter that are disposed on a substrate, a low refractive index layer disposed on the substrate, the first color filter, and the second color filter, the low refractive index layer including at least one of a first blue pigment and a first blue dye, a first color conversion layer overlapping the first color filter and including a semiconductor nanocrystal, a second color conversion layer overlapping the second color filter and including a semiconductor nanocrystal, and a transmissive layer that overlaps the low refractive index layer.

  • Publication number: 20240040815
    Abstract: A color conversation panel according to an embodiment may include partitioning walls disposed on a substrate, reflective layers disposed on outer surfaces of the partitioning walls, overcoats disposed outside on outer surfaces of the reflective layers and having water repellency, a spacer overlapping a part of the partitioning walls and protruding from a part of the overcoats, the spacer and the overcoats being formed on a same layer, and color conversion layers disposed on the overcoats and disposed in areas defined by the partitioning walls.

  • Patent number: 11830965
    Abstract: A display device includes a first light emitting element which overlaps a first light emitting region, and emits first color light, a first wavelength conversion pattern which overlaps the first light emitting element, and wavelength-converts the first color light into a second color light, and a first color filter which overlaps the first wavelength conversion pattern, and includes a first light absorbing colorant and a colorant of the second color, where the colorant of the second color blocks transmission of the first color light and transmits the second color light, where the colorant of the second color transmits light in a first overlapping wavelength range in which a first emission spectrum of the first wavelength conversion pattern overlaps a first light absorption spectrum of the first wavelength conversion pattern, and where the first light absorbing colorant absorbs the light in the first overlapping wavelength range.
