摘要

A display panel including a light emitting panel; and a color conversion panel with a surface opposite a surface of the light emitting panel. The light emitting panel is configured to emit incident light including a first light and a second light. The color conversion panel includes a color conversion layer including two or more color conversion regions, a color conversion region includes a first region corresponding to the green pixel, the first region includes a matrix and a first composite dispersed within the matrix and including a plurality of luminescent nanostructures, and the spectral overlap between a UV-Vis absorption spectrum of the luminescent nanostructures, the maximum emission peak of the first light, and the maximum emission peak of the second light satisfies the following equation: B/A≤about 0.6 A and B are as defined.
