Abstract

A color conversion panel includes a color conversion layer including a color conversion region, and optionally, a partition wall defining the region of the color conversion layer. The color conversion region includes a first region corresponding to a green pixel, and the first region includes a first composite that is configured to emit a green light and includes 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, and the zinc chalcogenide includes zinc, selenium, and sulfur. The luminescent nanostructures do not include cadmium. and at least a portion of surfaces of the luminescent nanostructures includes the second semiconductor nanocrystal. The emitted green light has a full width at half maximum of a maximum luminescent peak of less than or equal to about 42 nm.
