摘要： A display panel includes a color conversion panel and a light emitting panel, the light emitting panel includes a light emitting device that includes a first electrode, a second electrode, and a blue light emitting unit that includes an organic light emitting layer and is disposed between the first electrode and the second electrode and is configured to emit blue light. The color conversion panel includes a color conversion layer including at least two color conversion regions, and optionally, a partition wall defining that at least two regions, wherein the color conversion region includes a first region corresponding to a green pixel, a second region corresponding to a red pixel, and optionally a third region corresponding to a blue pixel. The first region includes a first composite including a matrix and a plurality of first semiconductor nanoparticles dispersed in the matrix, the first semiconductor nanoparticles includes a Group I-III-VI compound including silver, indium, gallium, and sulfur, and is configured to emit green light.
