Abstract: A color conversion panel that includes a color conversion layer including one or more color conversion regions, and optionally, a partition wall defining the regions of the color conversion layer, and a display device including the same. The color conversion region includes a first region corresponding to a first pixel, and the first region includes a first composite including a matrix and a plurality of luminescent nanostructures dispersed in the matrix. The luminescent nanostructures include a first semiconductor nanocrystal including a Group III-V compound and a second semiconductor nanocrystal including a zinc chalcogenide. The Group III-V compound includes indium, phosphorus, and optionally, zinc or gallium, or zinc and gallium, and the zinc chalcogenide includes zinc, selenium, and sulfur. The luminescent nanostructures do not include cadmium. The luminescent nanostructures further include fluorine, and in the luminescent nanostructures, a mole ratio of fluorine to indium is greater than or equal to about 0.05:1.
