1. A display panel, comprising
a light emitting panel comprising a plurality of light emitting units; and
a color conversion panel comprising a surface opposite a surface of the light emitting panel,
wherein the plurality of light emitting units comprises a first light emitting unit and a second light emitting unit,
wherein the color conversion panel comprises a color conversion layer comprising a first color conversion region and a second color conversion region, and a partition wall defining the first color conversion region and the second color conversion region,
wherein the first light emitting unit and the second light emitting unit are configured to provide the first color conversion region and the second color conversion region, respectively, with an incident light of an intensity of greater than or equal to about 10,000 candelas per square meter and less than or equal to about 17,000,000 candelas per square meter,
wherein the first color conversion region comprises a first semiconductor nanoparticle-polymer composite comprising a first polymer matrix and first semiconductor nanoparticles dispersed in the first polymer matrix, and the first semiconductor nanoparticle-polymer composite is configured to convert the incident light to a first light,
wherein the second color conversion region comprises a second semiconductor nanoparticle-polymer composite comprising a second polymer matrix and second semiconductor nanoparticles dispersed in the second polymer matrix, the second semiconductor nanoparticle-polymer composite is configured to convert the incident light to a second light, and the second light has a maximum luminescent peak wavelength different from the first light,
wherein the first color conversion region and the second color conversion region each independently have a light incident area of greater than or equal to about 1 square micrometer and less than or equal to about 1,000 square micrometers,
wherein the first polymer matrix comprises a polymer comprising a unit having a carboxyl group or an anion form of a carboxyl group,
wherein the first semiconductor nanoparticle-polymer composite further comprises an additional metal substance distributed in the first polymer matrix, and
wherein the additional metal substance comprises a Group IIB metal, a Group IIIA metal, or a combination thereof.
